Last Run Publisher's Summary
Cathy is also a runner, and she's vulnerable. As Sam and his team start to investigate, a connection emerges with another homicide, and others are drawn into the web.
With the killing spree continuing, Sam fears for the safety of his close-knit family, especially for his wife Grace, now blissfully pregnant after repeated miscarriages. Then a brutal attack on a loved one forces Sam to put his career and his own life on the line to stop the killer from striking again.
