Showing Slow Burn by Heather Graham

Faced with the brutal murder of her husband, Spencer Huntington demands answers from the one man who should have them--ex-cop David Delgado, her husband's former partner and best friend. And her former lover.

Spencer and David are bound by a reluctant partnership and find their loyalties tested by desires they can't deny. Their search takes them from the glittering world of Miami high society to the dark, dangerous underbelly of the city--while around them swirl the tortured secrets and desperate schemes of a killer driven to commit his final act of violence.
