Nancy J. Cohen's Bad Hair Day mysteries are a cut above the rest—rich, full, and stylish. Now her beautician-sleuth Marla Shore puts down her curling iron and picks up her skills at detection when she books passage on a cruise ship with a killer aboard. Soon it is full steam ahead toward mayhem and murder—in a case sure to have Marla going off the deep end. Scissor-wielding sleuth Marla Shore is looking forward to a leisurely cruise with her fiancé Dalton Vail. Too bad Dalton's teenage daughter and his parents are along for the ride. Instead of a seduction at sea, Marla is meeting the in-laws and hoping nothing goes too wrong. It is a vain hope. A mysterious envelope stuck into her cabin door read: "I know what you did and I have what you want." If it had not been addressed to "Martha" Shore and obviously delivered by mistake, Marla might have feared it referred to the nudie pictures buried in her past. But that embarrassment would have been better than what the note does foretell: Troubled water lies ahead. So instead of cruise control, Marla's on high alert, searching for the note's intended recipient before the cruise goes down the drain. If Marla does not find the culprit fast, this spunky stylist could end up with her own split end: caught between the devil and the deep blue sea.
