Something Borrowed, Something Black (Peter Macklin, The Nine-to-Five Killer, Book 4) [signed] [first edition]

Peter Macklin, contract killer--retired--has found himself the perfect woman. He's convinced young, beautiful, innocent Laurie that he is simply a salesman from Detroit, and they're passionately honeymooning in Los Angeles. . . . until the phone call. Peter tells Laurie he has to go to Sacramento to take care of business, and he'll be back in a day. After a day passes, though, a man called Abilene shows up with a note from Peter saying Abilene will take care of her until his return. Macklin's retirement seems to have been premature, and Laurie's innocence is about to end . . .
