Blue Smoke and Murder - Elizabeth Lowell

Jill Breck was just doing her job as a river guide when she saved the life of the son of two of St. Kilda Consulting's premier operators. But when a string of ominous events -- including a mysterious fire that kills her great-aunt and a furor in the Western art world raised by a dozen Breck family paintings -- culminates in a threat to her life, Jill finally calls in a favor.

Zach Balfour works part-time as a consultant for St. Kilda. Though he's got the skills to be a highly effective bodyguard, being a bullet catcher isn't his preferred way to spend time. But Jill is in deeper waters than she's ever known, and she'll need his protection; as she soon discovers, the perils of running wild rivers are tame compared with the hidden dangers in the high-stakes game of art collecting. Together, Zach and Jill must race against time to unmask a ruthless killer hidden in the blue smoke of money, threats, lies, and death. . . .
