The Marlow Murder Club (2021)

Judith hears a shooting while swimming in the Thames, then joins forces with dog walker Suzie and vicar’s wife Becks. Their different routines open up different parts of Marlow, giving the amateur investigation a useful social foundation. Thorogood keeps the puzzle moving while the unlikely friendship takes shape. Start with this first case for the trio’s beginning; the tone is comic, but a killer places them in real danger.
