The breaker

"A man wanted by two governments, Peter Ash has found a simple, low-profile life in Milwaukee, living with his girlfriend June and renovating old buildings with his friend Lewis. Staying out of trouble is the key to preserving this fragile peace . . . but when Peter spots a suspicious armed man walking into a crowded market, he knows he can't stand by and do nothing. Peter does interrupt a crime, but it wasn't at all what he'd expected. The young gunman appeared to have one target and one mission--but when he escapes, and his victim vanishes before police arrive, it seems there is more to the encounter than meets the eye. Peter's hunch is proven correct when a powerful associate from his past appears with an interest in the crime, and an irresistible offer: if he and June solve this mystery, Peter's record will be scrubbed clean."--
