'Pure catnip for budding young sleuths' The Telegraph

The first children's murder mystery from number-one-bestselling author of The Appeal, Janice Hallett, perfect for fans of Robin Stevens and Rhian Tracey.

When Ava and Luke discover a mysterious box of papers in their attic they are instantly curious about secrets it might hold. As they read through letters, diary entries, newspaper cuttings and listen to secret recordings, they realize that a decades-old, still unsolved, murder mystery is unfolding right in front of them . . .

Ava and Luke decide to try and crack the case themselves. But as they work through the clues, it soon becomes clear that the mystery isn't something left in the past: the killer is still out there - and might be closer than they think...

YOU know the facts. YOU have all the clues. Can YOU solve the mystery before they do?

Look out for DEATH AT THE MUSEUM, the next book in the A Box Full of Murders series, coming June 2026!
