Past Crimes (Van Shaw 1) by Glen Erik Hamilton
Van Shaw was raised by his Irish immigrant grandfather Donovan to be a thief--to boost cars, beat security alarms, and crack safes. But at eighteen, Van broke all ties to that life and joined the military, serving as an Army Ranger in Iraq and Afghanistan. Now, after ten years of silence, Dono has asked his grandson to come home to Seattle.
Van is curious and a little unnerved by his grandfather's request. But when he arrives at Dono's house, Van discovers his grandfather bleeding out on the floor from a gunshot wound to the head. With a lifetime of tough history between him and the old man, the battle-tested Ranger knows he'll be the first suspect.
To clear his name and avenge his grandfather, Van plunges back into a violent, high-stakes world where right and wrong aren't defined by the law . . . and where the secrets held by those closest to him are the deadliest of all.
