Hidden Deception — Leann Harris

Her own father had killed her mother. Afterward, Elena Segura Jackson had been adopted by a loving Santa Fe family. For years she'd tried to focus only on the present and future--not the past. But now another murder, in her family's antique shop, brings the old memories rushing back. Detective Daniel Stillwater, widowed father of a little girl, vows to find the killer. In Daniel's presence, Elena dares feel safe. Yet the killer keeps coming back, wreaking havoc in the shop, looking for...something.

Like a moment when the good detective isn't by Elena's side.
