The Final Detail by Harlan Coben

In this sixth novel in the award-winning Myron Bolitar series, Harlan Coben delivers a riveting powerhouse thriller--a twisting mystery of betrayal, family secrets, and murder. Myron Bolitar's colleague at MB SportsReps, Esperanza, has been arrested for the murder of a client, a fallen baseball star attempting a comeback. Myron is determined to prove Esperanza's innocence--even if she won't speak to him on the advice of her lawyer, who warns Myron to keep away from both the case and his client. But Myron is already too close, too involved, and has too much at stake. And the closer Myron gets to the truth, the more the evidence points to the only viable suspect besides Esperanza: Myron himself.
