Five O'Clock Twist (Inspector Rebecca Mayfield Series #5) by Joanne Pence
A foggy night. A dog's bark. This one just turned personal ...
Homicide Inspector Rebecca Mayfield hopes to come to terms with her confused emotions over alluring but troubling boyfriend Richie Amalfi, but her plans quickly change when her neighbor is viciously attacked. And it seems one of Richie's former girlfriends holds the key to the situation. As the body count grows, Rebecca's investigation takes a deadly turn when she becomes the killer's target.
Rebecca and Richie find themselves on a danger-filled route from a cold and foggy Pacific Ocean beach to the chambers of City Hall to the back alleys of San Francisco's Chinatown. Between killers on-the-loose, plus new as well as old "friends" to deal with, Rebecca isn't sure which one of them might prove to be the biggest threat to her life … or to her heart.
