The series
At a glance.
Lisa Thompson's Goldfish Boy mysteries follow the young detectives of Chestnut Close through a series of page-turning whodunnits, each narrated with real empathy. The first book puts housebound, OCD-stricken Matthew Corbin at the heart of a missing-child mystery he must solve from his bedroom window; the companion books hand the spotlight to Melody and reunite the friends for a graveyard spy puzzle and an unearthed-skeleton case. Every mystery genuinely puzzles, yet each is really about something quieter - the roots of Matthew's anxiety, learning who you can trust after a parents' break-up, a family under strain from illness. Thompson handles mental illness and grief with rare care while keeping the tension taut. Best read from The Goldfish Boy onward, though each stands alone.

Start with The Goldfish Boy; the companion mysteries reuse the Chestnut Close friends and read best in publication order, but each solves its own case.

The Chestnut Close mysteries
Three empathetic Chestnut Close whodunnits about anxiety, trust and families under strain.
Each Goldfish Boy book is a self-contained mystery starring the friends of Chestnut Close, so this collection covers the series to date. The Goldfish Boy sets housebound, OCD-stricken Matthew at the centre of a missing-toddler case he must crack from his window; The Magpie Riddle follows Melody as she decodes graveyard riddles with a boy claiming to be a spy, learning who to trust after her parents' break-up; The Skeleton Puzzle reunites the friends over an unearthed skeleton, a suspected imposter and a family strained by illness. Every book is a genuine page-turner wrapped around an honest look at anxiety, grief and family. Handled with Thompson's trademark care, the sensitivity is moderate throughout - warm and reassuring, but real.
