What’s it about?

The story.

Melody Bird loves the quiet of the graveyard, so when she discovers an abandoned house in its far corner she can't resist exploring, and finds a boy called Hal hiding inside. Hal says he's a spy-in-training, using the house as a base to keep watch on a dangerous local criminal, and he needs Melody's help to decode the strange riddles he keeps finding among the headstones. Melody, still wary of being lied to after her parents' break-up, wants desperately to believe him, but her friends Matthew and Jake are convinced Hal is hiding something. So they turn the tables and start spying on the spy, and the closer they get to the truth the bigger the mystery becomes. A companion to Lisa Thompson's bestselling The Goldfish Boy (first published as The Graveyard Riddle), this is a warm, twisty middle-grade mystery about riddles, secrets and the hard work of deciding who deserves your trust, starring the friends from Chestnut Close.

Where it lands by age

Why kids love it

Melody finds a real spy hiding out in a graveyard, complete with riddles to crack, but is he telling the truth? Turning the tables to secretly investigate him is brilliantly satisfying, and the codes and clues keep you guessing right up to a twist you won't see coming.

  • Being a detective
  • Having a secret base
  • Trickery and cleverness

Why parents love it

A satisfying whodunnit that quietly explores why Melody finds it so hard to trust, after her parents' separation, without ever slowing the puzzle down. It carries the same warmth and craft as The Goldfish Boy and works equally well read alone or aloud.

Lisa Thompson

Writer · United Kingdom

Lisa Thompson is an English children's author from Havering who worked at the BBC before her bestselling debut, The Goldfish Boy, in which a boy whose severe OCD keeps him housebound becomes the last person to see a missing toddler alive and must solve the mystery from behind his bedroom window. It stands as one of the most empathetic portraits of childhood OCD in middle-grade fiction. Its companion mysteries, The Magpie Riddle and The Skeleton Puzzle, return to the young detectives of Chestnut Close for twisty whodunnits about riddles, buried secrets and learning who you can trust. Across her work Thompson pairs a genuine page-turning plot with quiet, honest attention to anxiety, grief and families under strain, treating mental health with rare care while never letting the mystery slacken.
