Deadly Force (Paperback, Original ed.)

"It was his most personal cold case...and it was about to be reopened"
It was the one case Detective Sam Vernelli couldn't solve: the murder of his fiancee more than a decade ago. So he's not about to let her determined younger sister, Claire Fontaine, go it alone against whomever is threatening her in ways frightening and all-too-familiar. But protecting her means challenging Claire's angry doubts about him, understanding her deepest fears...and letting her get much too close as every dead-end lead pushes their fragile trust to the breaking point. Sam slowly begins to realize that the truth lies closer to home than either of them ever imagined--and the price of revealing it could be more than they bargained for.
