An alleged stalker.
A six-character alphanumeric on a scrap of yellow paper.
A murdered civil rights attorney.
A disappearing client.
And then that destiny thing.

For Friday Harbor P. I. Scotia MacKinnon life is as good as it gets until she takes on a new client. Elyse Montenegro has lost a husband, a Berkeley civil rights attorney. The police are clueless. Elyse claims she’s being stalked and now there is the unexplained island death of Elyse’s best friend. Scotia’s search into the past –aided by IT guru Zelda Jones and Friday Gazette publisher Jared Saperstein – will uncover a tangled thread of dark family secrets stretching from San Francisco Bay to a remote cabin in the mountains of Idaho. When the killer surfaces on the rocky island in a gathering winter storm, it might not be Scotia’s destiny to make it out alive.






San Juan County Sheriff Nigel Bishop announced today he is abandoning the search for Tina Breckenridge of Friday Harbor, whose 38-ft. sailboat was found abandoned near Sucia Island . . .Tina is survived by her husband Paul Breckenridge and her son Stephan.

Scotia Mackinnon’s client, photographer M. J. Carlye, doesn’t believe his sister’s drowning was a freak accident. Tina grew up on a boat. She built boats, she raced boats. She crewed on a crab fishing boat out of Dutch Harbor in the Aleutians. For the Friday Harbor P.I. and long-time sailor, something doesn’t compute. Juggling her romance with a Seattle maritime attorney, Scotia takes the case. Whereupon the cyberthreats begin, the island septuagenian lands in the jail, and a body turns up at Brown Sugar Beach. When Zelda’s friend Rafie finds the courage to ignore a death threat, it appears the answers to Tina’s drowning can only be found in one place: the dark waters of Desolation Sound.

All despite the fact that the prosecution was never able to establish that a murder had actually occurred. No body, no eyewitnesses.

Scotia client is a candidate for County Council against newcomer Lochlan McCready, a former CIA operative who is dredging up the 30-year old murder conviction and leaving no skeleton unturned to win the election.
