Cosy crime lives or dies on its setting, and a charity shop is an inspired one: a place the whole neighbourhood passes through, where objects arrive with their histories still attached, and where the volunteers behind the till hear absolutely everything. Peter Boland built a mystery series on that premise, and the idea does a great deal of the work before a body is even found.
The furniture of the genre is unmistakably British here: high street bric-a-brac, amateur sleuths who ought to know better, a tone that keeps menace at arm’s length and puts character in the foreground. It is written for listeners who want a puzzle to solve in good company rather than a thriller that leaves them checking the locks.
