Children’s Puzzle Writer – Create 50 Detective Mystery Cases

I am looking for an experienced children’s puzzle writer and/or activity book creator to develop 50 original, immersive detective mystery cases for children aged 7–9. The working tile of teh book is 'The Holiday Detective Activity Book for Kids Ages 7–9”'.

This is not a story book but a kids activity book for school holidays based on solving mysteries .
The aim of this book is to make children feel like they are real detectives solving mysteries, rather than simply completing standard activity book puzzles.

This should NOT feel like a typical kids’ activity book filled with word searches, crosswords, or random puzzles.

Core Creative Requirement:

**Each case should:
Make the child feel like a detective investigating a mystery
Be driven by a storyline with clues
Encourage logical thinking, deduction, and reasoning
Feel purposeful and investigative rather than “puzzle for puzzle’s sake”

**Not all cases need to use traditional puzzles. Some mysteries may be solved through:
Process of elimination
Careful reading of clues
Logical reasoning based on evidence
Comparing statements from suspects

**In some cases, the child may be given:
A list of suspects
A set of clues or witness statements
A timetable, map, or simple diagram

**The child should use these to work out:
Who did it
What happened
Where or when it happened

**Scope of Work
You will create 50 unique detective cases, each including:
Case Title - Fun, mystery-themed, age-appropriate
Short Storyline / Scenario
Engaging and easy to read
Positive, child-friendly tone
No violence, crime, or dark themes
Relatable everyday situations for children

**Investigation Method
Each case should clearly explain how the child investigates the mystery, which may include:
Solving an integrated puzzle
Eliminating suspects based on clues
Matching evidence to characters
Reasoning through statements or timelines

** Interactive Elements
Each case must include opportunities for children to:
Write notes
Circle or cross out options
Draw lines or arrows
Complete tables, checklists, or grids

**Solution & Explanation
Clear and unambiguous final answer
Short explanation showing how the clues lead to the solution

**Puzzle & Content Guidelines
Target age: 7–9 years
All content must be 100% original
Black-and-white interior only
No colour-dependent logic
Avoid overused activity book formats such as: Word searches; Simple crosswords; Random mazes; Standalone cryptograms
Puzzles or investigative methods should always feel meaningful to the story.

** Themes
Cases should be relatable and suitable for school holidays, such as:
School and clubs
Family and friends
Pets and animals
Sports and hobbies
Travel and days out
Seasonal and holiday situations

**Design & Illustration
Design/illustration skills are not required as a separate designer may be hired, however would be a bonus if the puzzles could also be illustrated.

** Ideal Freelancer would have:
Experience writing for children (especially ages 7–9)
Experience with activity books, puzzle books, or educational content
Strong storytelling and logical thinking skills
Clear, friendly writing style

To Apply, Please Include

A brief description of your relevant experience
Examples of previous children’s work (if available)
A short sample detective mystery idea

I AM OK WITH THE USE OF AI TO HELP WITH THIS PROJECT BUT PLEASE DO NOT JUST GIVE A CHAT GPT SAMPLE ABOUT A MISSING LUNCH BOX OR MISSING LIBRARY BOOK.
The mysteries while aimed at kids age 7-9 shouldn't be too simplistic. They need to use their logic skills to solve. They shouldn't be able to solve the mystery in 5 mins. This is a school holidays activity book that should keep them occupied.
