Race Against Time by Christy Barritt

Were it not for her cop neighbor, widowed mother Madison Jacobs would be dead. Thankfully, Detective Brody Philips interrupts an attempt on her life in the nick of time. But the would–be killer hasn't given up, and each tick of the clock brings the madman closer to finishing what he started. Brady vows to catch the serial killer plaguing the sleepy Virginia town…especially when he realizes the danger has followed him from the big city. With everyone around him at risk, it'll take everything Brody's got to do his duty and keep Madison and her son safe.
