Verity Beresford is worried about her husband. Oliver didn’t come home last night so of course Verity goes straight to Judith Potts, Marlow’s resident amateur sleuth, for help. Oliver, founder of the Marlow Amateur Dramatic Society, had hired The Marlow Belle, a private pleasure cruiser, for an exclusive party with the MADS committee but no one remembers seeing him disembark. And then Oliver’s body washes up on the Thames with two bullet holes in him – it’s time for the Marlow Murder Club to leap into action.
Oliver was a rather complicated chap and he wasn’t short of enemies. Judith, Suzie, and Becks are convinced they’ll crack the case in no time. But things are not as they seem in the Marlow Amateur Dramatic Society, and the gang will need to keep their wits about them, otherwise a killer may sail away scot-free …
