What would you do if a locked box appeared on your desk with your name on it? Write a short mystery in which one clue leads to a reveal that makes sense.
By Mr. Alexander · Middle school writing

I can connect a clue to a reveal so my short mystery is clear and suspenseful.
- I write 4–6 connected sentences.
- A clue matters later in the story.
- The ending follows from what I wrote.
Story starter: There was a small locked box sitting on my desk when I got home. My name was written on it in handwriting I did not recognize.
Continue the story in 4–6 sentences. Answer two questions through the action: What clue does the character notice? What is inside the box, and why does it matter?
Sentence starter: “At first I thought ___, but then I noticed ___.”
A quick way to plan
Clue means a detail that helps the reader understand or predict what happens. Suspense is the uncertainty that makes a reader want to continue. You do not need several twists. One strong connection is enough.
Worked example with a different mystery
Different prompt: A sealed envelope is taped beneath a chair. “The envelope felt empty, but the back showed a faint map of the library. I followed the map to a loose shelf label. Behind it was a note in my sister’s handwriting: ‘Meet me where our favorite story ends.’ The map mattered because it led to the message instead of appearing as a random detail.”
The example plants one clue, shows a choice, and pays off the clue. Use that pattern, but invent your own box, clue, and reveal.
Optional stretch challenge
Add one precise action, thought, or line of dialogue that slows down the moment just before the box opens.
Check and revise before submitting
- Underline the clue and circle the part of the ending it connects to.
- If the ending feels random, add one earlier detail that prepares the reader.
- Check capitalization, punctuation, and spelling.
