The fourth Merry Folger nantucket mystery
 
After a trying case, detective Merry Folger begrudgingly agrees to take a leave from work to meet her fussy future in-laws in Greenwich, but it isn’t long before she is summoned back to Nantucket. The body of a 21-year-old was discovered in the frigid waters of the Sound in the days leading up to the annual Christmas celebration, and the death isn’t sitting well with Merry’s father, the local police chief, who fears the track marks on the victim’s arms may be indicative of a growing drug problem on the island. Feeling a constant need to live up to her father’s expectations, Merry rushes home to her fiancé, Peter’s, annoyance, only to find that heroin isn’t the only destructive force in Nantucket.
 
Soon after Merry arrives, she feels stonewalled by her father. If he was so desperate for her help, why won’t he share the details of the case with her? What is he hiding? For the first time, Merry fears she cannot trust her lifelong role model—her own father—let alone figure out why a young athlete and Harvard scholar ended up dead in the frigid, storm-churned Sound.
