December's Secrets (Larry Macklin Mysteries Book 2)

Still smarting from his disastrous last date with Cara Laursen, criminal investigator Larry Macklin is nevertheless thrilled to get a call from her. But when he arrives at her house, he finds the chief suspect in his latest murder case sitting in her living room—her father, Henry.
Henry claims he is being framed and Larry wants to believe him, but evidence suggests otherwise. And when another murder occurs with direct links to Henry, Larry can’t stop him from being taken into custody.
For Cara’s sake, Larry will do anything to prove Henry’s innocence, but will he have to sacrifice his own ethics and risk obstructing justice in order to do it?
