No good deed goes unpunished in the fourth Zack Walker mystery thriller from Barclay, which finds the newspaper reporter, family man and very reluctant hero just settling back into a semblance of middle-class normalcy after his last adventure (2006's Lone Wolf
). That all changes when Zack tries to help good friend, former neighbor and professional dominatrix Trixie Snelling dissuade local tabloid reporter Martin Benson from running a story on her and her business. Not long after Zack tries, unsuccessfully, to persuade Martin to pull the story, Martin turns up dead, tied to a rack with his throat slit, in Trixie's bondage basement—and Trixie, the prime suspect, has disappeared. Zack sets off in search of answers, following a path deep into Trixie's troubled, violent past that could cost him his job, his family and his life. Barclay has a fine ear for dialogue, especially in scenes with Zack and his family, and his expert blend of humor and suspense make this a well-constructed, often witty mystery that's sure to please.
