The Wrong Quarry [EPUB ebook] 

A HIT. AND A MISS. Quarry doesn’t kill just anybody these days. He restricts himself to targeting other hitmen, availing his marked-for-death clients of two services: eliminating the killers sent after them, and finding out who hired them…and then removing that problem as well. So far he’s rid of the world of nobody who would be missed. But this time he finds himself zeroing in on the grieving family of a missing cheerleader. Does the hitman’s hitman have the wrong quarry in his sights? The Critics Love QUARRY 'Violent and volatile and packed with sexuality…classic pulp fiction.’ — USA Today 'Collins’ witty, hard-boiled prose would make Raymond Chandler proud.’ — Entertainment Weekly
