Trouble is stirring when murder comes wrapped in the guise of a seascape painting. The gift from a close friend who deals in art becomes a mystery to solve after Izzie and Chloe Abbington accidently discover that hidden behind the seascape is a priceless Vermeer which many would kill to possess. When the seascape with its hidden masterpiece is stolen, and a murder hits too close to home, their friend is accused of the crime.

Determined to help clear his name, Chloe and Izzie follow the clues, which take them beyond the comforts of their small town community and into the art world's unsavory side. However, the more they learn, the more guilty their friend looks. They question many involved, both dealers and collectors, as well as the patrons of the arts group their parents belong to, but everyone has their secrets. Even the seascape has a story to tell, if only the sister duo can decipher the details. Troubled and frightened of what they'll uncover, Chloe and Izzie won't stop searching for answers, even if the killer turns out to be someone they know.
