Robert B. Parker's Blind spot / Reed Farrel Coleman.

Enhanced descriptions from Syndetics:

"Coleman keeps the characters and the somber atmosphere but makes the book his own stylistically." -- Booklist
Police Chief Jesse Stone is back in the remarkable new installment of the New York Times–bestselling series.
 
It's been a long time since Jesse Stone left L.A., and still longer since the tragic injury that ruined his chances for a major league baseball career. When Jesse is invited to a reunion of his old Triple-A team at a hip New York city hotel, he is forced to grapple with his memories and regrets over what might have been.

Jesse left more behind him than unresolved feelings about the play that ended his baseball career. The darkly sensuous Kayla, his former girlfriend and current wife of an old teammate is there in New York, too. As is Kayla's friend, Dee, an otherworldly beauty with secret regrets of her own. But Jesse's time at the reunion is cut short when, in Paradise, a young woman is found murdered and her boyfriend, a son of one of the town's most prominent families, is missing and presumed kidnapped.

Though seemingly coincidental, there is a connection between the reunion and the crimes back in Paradise. As Jesse, Molly, and Suit hunt for the killer and for the missing son, it becomes clear that one of Jesse's old teammates is intimately involved in the crimes. That there are deadly forces working below the surface and just beyond the edge of their vision. Sometimes, that's where the danger comes from, and where real evil lurks. Not out in the light—but in your blind spot.
