No nine-to-five cubicle career will suit Stacie Calderβthe naturalist much prefers working in the great outdoors. Specifically, the spacious and spectacular Alaskan wilderness, whose rugged charms she shares with sightseers on the top deck of the tour boat where she works. But one May afternoon, Stacieβs passengers see more than glittering glaciers, frolicking harbor seals, climbing bears and soaring seabirdsβ¦they also witness a man lying dead in the frigid Alaskan waters. And it seems likely that someone gave him a fatal push. Β Stacie didnβt know the unfortunate victim, but he sure wanted to know a lot about her. He spent most of his final afternoon bombarding her with questions quite awkward to answer. And when he wasnβt in her hair, he was arguing incessantly with the boatβs beleaguered crew. Which makes for a suspect list about as long as the passenger manifest. Furthermore, as police helicopters relentlessly circle her boat in search of any clues, Stacie is shaken to find herself on that suspect list. Β Before the tour boat reaches shore Stacieβaccompanied by her beautiful blue-eyed husky, Sashaβmust deduce just who sent the testy tourist tumbling into the turgid waters and have the authorities take custody. Because if she canβt, then the killer might aim a fatal ice-cold stare at Stacie.
