Nothing Personal — Peter Chambers

Heather Dentman had written love letters which fell into the wrong hands, and now she was being blackmailed. She wasn't afraid of her husband, but of her strait-laced mother-in-law Cecile, who would tighten the purse-strings if she found out. Mark Preston got the assignment, but instead of the letters, all he found was a corpse - and three tough characters from the East, who seemed to think he would also look well in the morgue.
