When the Thrill Is Gone

Mosley fills his third thriller featuring New York City PI Leonid McGill (after Known to Evil) with insights even deeper than the mysteries McGill is trying to solve. Chrystal Tyler, a potential new client, tells McGill that she's afraid her billionaire husband is having an affair and may kill her. While McGill realizes the woman is lying, he needs the case and agrees to see what he can do to make her husband back off. Meanwhile, McGill's wife of 24 years, Katrina, is having an affair; his favorite son, Twill, has a new scam working; and longtime boxing mentor Gordo Tallman is living in his apartment, fighting cancer. Then Harris Vartan, a dangerous organized crime figure, asks a favor that will lead McGill on a journey of self-discovery. Readers will encounter the full panoply of complex Mosley characters, from deceitful women to ruthless killers, but it's the often surprising bonds of love and family that lift this raw, unsentimental novel.
