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.

Why they love it.

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.

  • Conversation starter
  • Great writing
