Felicity Koerber’s bean to bar chocolate shop on Galveston’s historic Strand is expanding, as it has become a gathering spot for the community, despite having been the scene of multiple murders. Artists she met while doing a chocolate sculpture are now working out of the shop. So when Felicity is invited to tea by an eccentric art collector, she’s intrigued, especially when she gets asked to pose for a portrait done with chocolate on chocolate. However, when a murder takes place the next day at the same historic house where the tea was held, one of Felicity’s artist friends becomes the main suspect.

When the killer threatens that, unless Felicity unravels the murder, one of her two love interests will be the next victim, she finds herself unwittingly at the center of a puzzle, with a Sherlock Holmes obsessed murderer who wants to be the next Moriarty – and wants to cast Felicity as Sherlock.

Felicity starts finding unexpected connects between her friends and acquaintances, and has to deal with the idea that someone who knows her is a murderer. At the same time, she has to keep her business running, despite construction dust and unruly customers – and an unexpected order for thousands of truffles.

Satchmo the retired police dog turned therapy dog returns to help her sniff out a few clues, and the kidnapping of Ruffles, the quirky artist’s cat, helps lead Felicity into the puzzle. Can Felicity solve it in time to protect the people she cares about from becoming additional victims?
