Homicide detective Jake Carrington has an engagement that can't wait--with a killer.   Haunted by the murder of his sister, Lieutenant Jake Carrington struggles to control his personal demons as he stands over the brutalized body of a young woman found dead on the railroad tracks. The victim disappeared on July 6th, the fifth woman in as many years to go missing on that date. The fifth happy bride-to-be. The only one whose body has turned up.   Soon the killer is sending personal messages to Jake. They refer to an unidentified brother he believes Jake hates as much as he does. With his partner distracted by turmoil at home, Jake is on his own. Drawn deeper and deeper into a murderous family feud, his mission is to find out who the killer's brother is--and stop him before another innocent woman's life is cut tragically short.   "Tense and authentic--a suspenseful page-turner!" --Leo J.
