A private detective and her dog investigate a cop’s death in this “page-turner” that will have “even die-hard mystery readers . . . guessing until the end” (Publishers Weekly).   Officer Timothy O’Fallon’s death may have been ruled an accident, but private investigator Rachel Alexander can’t let the details of his case go. Allegedly, the cop was cleaning his service revolver when it misfired—but why did he name Alexander as the executor of his will? O’Fallon was a stranger to her, a member of the 9/11 survivors group she went to with her pit bull Dashiell. Though he attended all the meetings, he never spoke a word. Outside of the single sentence O’Fallon uttered to her one night after he’d taken Dash for a walk around the block—returning the dog with his fur soaked in tears—Rachel knows nothing about him.    Now she’s calling the siblings he didn’t trust enough to settle his affairs to tell them the news of his sudden passing. And the more she searches through the details of his lonely life, prowling the corners of the Greenwich Village neighborhood they once shared, the more of a mystery he becomes.   Was his death a suicide? Or something more sinister? As Rachel sets about her work, she soon discovers the secrets in O’Fallon’s past that led to his tragic end. . . .   “One of the best private eye series around.” —Harlan Coben, #1 New York Times–bestselling author of Fool Me Once   “Benjamin’s work [is] first rate.” —The Plain Dealer
