A Deep Blue Farewell

Description for A DEEP BLUE FAREWELL by Sharon Duncan:

Private detective Scotia MacKinnon, an intuitive ex-cop, makes her home on a sailboat in the harbor of San Juan Island. There, in a tiny town in the upper reaches of the Pacific Northwest, Scotia meets up with big-time crime....

Scotia MacKinnon's new client just can't believe that his sister's death was a freak accident. But the authorities--with no body and no clues--have decided that Tina Breckenridge, a local sailing instructor, must have drowned near her abandoned boat. Scotia senses foul play, but after following dead ends and receiving threatening messages, she and Zelda, her flamboyant Web guru assistant, are ready to give up. Little do they know that their problems have only just begun. To understand Tina's final farewell, Scotia will have to sail through dangerous waters...to a place ominously named Desolation Sound.

This is #2 in A Scotia MacKinnon Mystery.
