HARD RAIN by David Rollins - SIGNED FIRST EDITION BOOK

Air Force Office of Special Investigations Special Agents Vin Cooper and Anna Masters arrive in Istanbul to investigate the gruesome homicide; as Vin puts it they are USAF internal affairs cops. However, before they can begin their inquest, other associates of the late Colonel are also killed in horrific ways. The obvious response is a serial killer is on the loose. However, the victims are diverse and vary in what is left behind; the only commonality is the abduction and execution are done with military precision..

With Portman's email being erased, Vin and Anna wonder why a crazed killer would do something of this sort making them wonder if someone needed to conceal something, but what and who remain elusive. As the two agents investigate on non-verbal terms (one can say a lot with a one finger salute) while the body count rises, they begin to uncover a military conspiracy to encourage coups to topple Middle Eastern governments, but neither is sure how to expose it without harming American interest; that is if they live long enough to do so.
