1. What is mystery writing?

A mystery story is built around a question that nobody can answer at first: something has gone missing, someone has disappeared, a strange message has arrived, or something happens that nobody can explain. A curious character — usually an ordinary person, not a real detective — looks for clues, follows some wrong ideas, and finally works out the truth.

Not every mystery is a crime. At Year 6, the best mysteries are often small and close to home: a missing ring, a lost pet, a secret in an old box, a note with no name. What matters is that the reader wants to know the answer and that the answer makes sense when it arrives.

	Mystery	Horror (spooky)
Main feeling	curiosity — "What happened?"	fear — "What is out there?"
Main character	an investigator who looks for clues	an ordinary person who is frightened
Ending	the question is answered and it makes sense	something is often left unexplained

Purpose: to puzzle and entertain the reader, and to give a satisfying answer at the end. Audience: the examiner, who should enjoy trying to solve the mystery with your character.

Where it sits in the exam

Paper 2 is the Fiction paper. It lasts 1 hour and is worth 50 marks: Section A Reading (25 marks) and Section B Writing (25 marks).
The suggested time for each section is about 30 minutes. That means you have about 30 minutes to plan, write and check your story.
Section B is one writing task. It can ask you to write the opening of a story, to continue a story, to write a complete story on a theme, or to describe a setting or character inside a story. It can be linked to the extract you read in Section A, and it usually gives you bullet points to include.
The task will not always say "write a mystery story". It gives you a theme. YOU decide that this genre fits the theme — then you stay inside the genre from the first line to the last.
Your story is marked by Cambridge examiners, not by your teacher, so it must make sense to a stranger who has never met you.

Themes that suit a mystery story: something important goes missing, a strange discovery, a secret, a message or map, a locked box or door, a person who is not what they seem, a special place that hides something.

How your story is marked (25 marks)

Mark category	Marks	What the top band looks like in this genre
Creation of texts	5	The story answers the theme and every bullet point. There is one clear question. Clues are given fairly, the investigator thinks and acts, and the answer makes sense. The reader is kept guessing until the end.
Vocabulary and language	3	Precise words for investigating (clue, suspect, noticed, examined, realised) and well-chosen description of the setting and characters.
Structure of texts (Text structure)	7	The six stages are clear. Clues are placed in the right order. The ending links back to details from earlier in the story.
Grammar and punctuation (Sentence structure, punctuation & grammar)	7	Questions, short and long sentences used for effect. Accurate speech punctuation, colons, dashes and ellipsis. Past tense throughout.
Word structure (spelling)	3	Common and harder words spelled correctly (disappeared, suspicious, believe, realised, separate, definitely).
Total	25	Marked by best fit: the examiner reads the whole story and chooses the band that describes it best in each row.

Rules that can cap your mark

20 words or fewer scores 0.
An answer of 21-60 words can get no more than 7 marks out of 25.
If you write the wrong text type (for example, a diary or a letter when the task asks for a story), Creation of texts can be capped at 1 and Structure of texts at 3 (sometimes 2).
If your story moves away from the task's theme or forgets a bullet point, you lose Creation marks even if the writing is lovely. Keep the bullet points in front of you.

2. Features of mystery stories

Feature	What it means	Example sentence
A central question	The one thing the reader wants to know	Who had taken the ring — and how?
An investigator	An ordinary, curious person who will not give up	I was not a detective, but I could not stop thinking about it.
Clues	Small, important details that help solve the mystery	There was flour on the windowsill.
A red herring	A false clue that points the wrong way	My cousin looked guilty — but he was only hiding biscuits.
Suspects	People who might be involved, each with a reason to seem guilty	The neighbour had been in the garden all morning.
Suspense	The answer is delayed; each discovery brings a new question	If the door was locked, how had it got out?
An interesting setting	The place that holds the secret	The kitchen was full of trays, bowls and sugar.
A twist	The story changes direction before the truth	It was not a theft at all.
A satisfying answer	The solution uses the clues the reader has seen	The ring had been inside the biscuit all along.

Language and layout features (these earn Structure and Grammar marks):

Feature	How to use it	Example
A title	Name the missing thing or the place	The Ring in the Kahk / The Empty Cage / The Note in the Library
Questions	Show the investigator thinking	Had she forgotten, just once?
Paragraphs	A new paragraph for each new clue or discovery	Then I noticed the dough.
Dialogue	Questioning suspects and sharing ideas	“Where were you at eleven o'clock?” I asked.
STEAL characterisation	Suspects show guilt or innocence through Actions and Looks	He kept his hands in his pockets.
Clue language	Verbs of noticing and thinking	noticed, examined, realised, remembered, wondered
Ellipsis	A pause just before an important idea	And she always put it… where?
Connectives of time and thinking	Show the order of the investigation	First, / Then, / However, / At last, / That was when I realised

Play fair with the reader

Every clue that solves your mystery must appear in the story BEFORE the answer. If the solution comes from nowhere ("Then a policeman told us who did it"), the reader feels cheated and you lose Creation and Structure marks. Plan your answer first, then hide two or three clues on the way.

3. How to structure a mystery story

Plan with G.C.S.P.P. — but for a mystery, plan the answer first. Genre (mystery — what is the question and what is the true answer?), Characters (the investigator + a helper or the owner of the missing thing + one suspect who is a red herring — 3-4 characters only), Setting (one place you know well: a home, a classroom, a garden, a library), Point of view (first person "I" works very well — the reader solves it with you), Plot (whole story, opening or continuation?).

Then follow the six mystery stages. In 30 minutes, keep each stage to one or two short paragraphs.

Stage	Paragraph(s)	What to write	Tip
1. Opening — something unusual	1	A short, clear hook: something is missing, wrong or strange.	"The morning before Eid, Grandma's gold ring disappeared."
2. The central mystery	2	Explain why it matters and why it is puzzling.	Make the reader care about the missing thing.
3. The investigator and the others	3	Introduce your investigator and the people around. One of them looks suspicious.	Use STEAL: a guilty look, a strange action.
4. Clues and a red herring	4-5	The investigator collects facts, asks questions and follows the wrong clue first.	The red herring should have an innocent, often funny, explanation.
5. Discovery	6	A new clue or a memory sends the investigator in the right direction.	Use a question: "Had she forgotten, just once?"
6. The answer and the ending	7-8	Reveal the truth, show how the clues fit, and show the investigator's feelings or what they learnt.	End with a final image, often light-hearted.

Minutes	What you do
0-4	Read the task twice. Underline the theme and every bullet point. Plan with G.C.S.P.P. (Genre, Characters, Setting, Point of view, Plot) and jot one note for each paragraph. Write the true answer and two clues in your plan first.
4-26	Write. Many strong answers are about 250-350 words. At minute 15 you should be at the problem (the middle of your story). If you are still describing the setting, move on.
26-30	Check: spelling of your best words and names, full stops (no long chains of commas), speech marks, capital letters, and the same tense all the way through.

The answer should be surprising AND obvious

A great mystery ending makes the reader say "Of course!" — surprising at first, but obvious once explained. That happens when the clues were there all along. In the sample, flour, sugar and dough are mentioned again and again, so the ring in the biscuit feels clever, not random.

4. Useful phrases and vocabulary

Change the words in brackets to fit your own story. Use one or two in each stage.

5. Strong sample answer

Mystery story — The Ring in the Kahk348 words · Strong answer — Creation 5/5 · Vocabulary 3/3 · Structure 7/7 · Grammar & punctuation 7/7 · Spelling 3/3

Task: Write a story in which something important goes missing. In your story you should: describe what is missing and why it matters, describe how a character looks for clues and explain how the mystery is solved.

The morning before Eid, Grandma’s gold ring disappeared.

It was not just any ring: Grandpa had given it to her fifty years ago. Now she stood in the kitchen with an empty hand and a face as white as flour.

“I had it at breakfast,” she said. “I’m sure of it.”

By lunchtime, the whole family was searching: Uncle Sami emptied every drawer and Aunt Hoda crawled under the sofa with a torch. Only my cousin Hassan did nothing; he sat in the corner with his hands in his pockets, looking guilty.

My name is Mariam, and I had read every detective book in our school library. I decided to solve the case.

First, I wrote down the facts: the ring was there at breakfast, Grandma had baked all morning and nobody had visited except the family.

Then I questioned my main suspect. “Hassan,” I said, “why are your pockets so full?”

His face turned red. Slowly, he pulled out two handfuls of crumbs — the crumbs of six stolen kahk biscuits.

“Please don’t tell Grandma,” he whispered.

So Hassan was a biscuit thief, not a ring thief. My best clue had led nowhere.

Back in the kitchen, trays of kahk were cooling on every surface, each one dusted with sugar. Then I remembered something. Grandma always took off her ring before she kneaded dough… and she always put it in the same place: the little china cup beside the sink.

The cup was empty. Had she forgotten, just once? Beside it sat a bowl of leftover dough — the dough for the very last tray.

My heart beat faster. One by one, I weighed the biscuits from that tray in my hand. The eighth one was heavier than the rest.

Gently, I broke it in half. There, shining in the middle, was Grandma’s gold ring.

Grandma laughed until she cried, Hassan was forgiven for the biscuits, and I was given the first kahk of Eid. Book detectives look for guilty faces. Real detectives, I decided, look for flour. Even so, I checked mine carefully before I took a bite.

Why this gets the marks

Creation of texts 5/5 — all three bullet points: what is missing and why it matters (Grandma's gold ring, a gift from Grandpa fifty years ago, paragraphs 1-3), how the investigator looks for clues (Mariam writes down the facts, questions a suspect and searches the kitchen, 5-13), and how it is solved (the ring is baked inside a biscuit, 14).
Creation — a fair mystery: the real clues are there for the reader too (Grandma baked all morning in paragraph 6, she always takes off her ring before kneading in 11, and there is a bowl of leftover dough in 12). A sharp reader can solve it just before Mariam does.
Creation — a red herring: cousin Hassan looks guilty with full pockets (4, 7), but he is only hiding stolen biscuits (8-10). The twist makes the story change direction before the truth.
Creation — the investigator changes: she starts as a girl who has read detective books (5) and ends with her own rule: "Real detectives, I decided, look for flour" (15). Characters are shown with STEAL: Hassan's Actions and Looks ("hands in his pockets, looking guilty", "His face turned red"), Grandma's Looks ("a face as white as flour").
Vocabulary 3/3 — precise words for a mystery: disappeared, suspect, facts, clue, kneaded, leftover, weighed, heavier. Imagery: simile "a face as white as flour" (2) — which also links to the solution.
Structure 7/7 — the six mystery stages: something unusual (1), the central mystery (2-3), investigator and characters (4-5), clues and a red herring (6-10), tension through discovery (11-13), reveal and resolution (14-15).
Structure — cohesion: flour and sugar appear across the story (2, 11, 15), so the ending feels planned. A short question in paragraph 12 ("Had she forgotten, just once?") turns the investigation towards the answer.
Grammar & punctuation 7/7 — sentence variety: a short hook sentence, a question in speech, a long sentence with three parts in the resolution (15), fronted adverbials ("By lunchtime," "Back in the kitchen," "One by one,").
Grammar & punctuation — range: colons for explanation ("not just any ring: Grandpa had given it…") and for a list ("the facts: the ring was there at breakfast, Grandma had baked all morning and nobody had visited…"), a semicolon joining two related sentences ("Hassan did nothing; he sat in the corner…"), a single dash for emphasis ("— the crumbs of six stolen kahk biscuits"), ellipsis for a pause before the key clue ("before she kneaded dough… and she always put it…"), and a split speech sentence ("“Hassan,” I said, “why are your pockets so full?”").
Spelling 3/3 — tricky words correct: disappeared, searching, guilty, questioned, suspect, whispered, kneaded, leftover, weighed, heavier, forgiven, carefully. Apostrophes accurate (Grandma's, I'm, don't).

6. Common mistakes and final checklist

Common mistake	Why it loses marks	Fix
The answer comes from nowhere ("Then the police told us.")	The investigator does nothing (Creation, Structure)	Your character must solve it by noticing clues.
No clues before the answer	The mystery is not fair to the reader	Hide two or three clues earlier in the story.
The mystery is too big (a bank robbery, a kidnapping)	Too much to solve in 300 words	Keep it small and close to home.
Too many suspects	Confusing	One red herring suspect is enough.
The red herring is never explained	Loose ends (Structure)	Show why that person looked guilty.
Long description before the mystery starts	No hook, wasted time	State the mystery in the first line or two.
Lots of "I think… I think… I think…"	Repetitive (Vocabulary)	Vary: I wondered / I realised / I noticed / It seemed that.
Mixing up the order of events	The reader cannot follow (Structure)	Use connectives: First, / Then, / Later, / At last,

Practice tasks

Practice task 1: Write a story about a strange discovery in a special place. In your story you should: describe the place and what is discovered, describe how the main character tries to find out more and explain what the truth is. Write a G.C.S.P.P. plan with the answer first.
Show answer
Answer first: the mysterious notes in the library books are from the old librarian, who is retiring and wants to thank the children who read most. G: mystery. C: Zeinab (11, reads every day), her friend Omar (thinks it is a ghost — red herring idea), Mr Hamdy the librarian. S: the school library, quiet and dusty, the top shelf of adventure books. P: first person, past tense. Plot — 1 hook: "The note was hidden inside page 50." 2 the note says "Thank you for coming back" with no name. 3 more notes appear in other books Zeinab borrows. 4 Omar thinks the library is haunted, so they wait after school (red herring). 5 clue: the notes are written in green ink, and the library stamp is also green. 6 Zeinab notices Mr Hamdy's green pen. 7 the answer: he is retiring, and the notes are his thank-you. 8 ending: Zeinab leaves her own note in his favourite book.
What is a red herring? Write one for a story about a missing class hamster.
Show answer
A red herring is a false clue that points the reader in the wrong direction. Example: the school cat is seen licking its lips beside the empty cage — everyone suspects it, but the hamster is later found asleep inside the teacher's warm slipper. The cat had only been drinking spilt milk.
Rewrite this ending so the investigator solves the mystery: "We could not find the key anywhere. Then Mum came home and told us it was in her bag."
Show answer
Possible answer: "Then I remembered the jingle I had heard when Mum hugged me goodbye that morning. I ran to the phone. “Mum,” I said, “check your coat pocket.” There was a pause… and then she laughed." — the investigator uses a clue (the sound) to solve it.
In the sample, why does the writer use the ellipsis in paragraph 11 ("before she kneaded dough… and she always put it in the same place")? Give all the possible effects.
Show answer
Possible answers: (1) it creates a pause, showing Mariam remembering and thinking. (2) it builds suspense, because the reader feels an important clue is coming. (3) it slows the reader down so the clue stands out. (4) it shows that her thoughts are moving towards the answer step by step.
In the sample, why does the writer use the simile "a face as white as flour" in paragraph 2?
Show answer
Possible answers: (1) it shows how shocked and worried Grandma is — her face has lost its colour. (2) it helps the reader picture her face clearly. (3) it fits the setting, because she has been baking. (4) it is a hidden clue, because flour and baking turn out to be the answer to the mystery.
