The deal goes down
(Book)

Ex-private eye Tony Casella lives in the Catskill mountains, a lonely old tough guy whose body can no longer do what it once did. His wife and son are dead; his daughter barely talks to him; his bank is in the process of foreclosing on his home. But a chance encounter with a rich young woman on a train changes everything. He is hired to take care of her superrich, sexual predator husband. That job leads to others and he joins a small start-up whose mission is to save women from abusive marriages. Provided their spouses are in the top 0.01%. It's a luxury service destined to make great profits. Tony's problems seem to be over, but are they? An old, angry associate is determined to get his cut of Tony's earnings, murky government agents start to tail him, and when he is sent to the Austrian alps to kill a Russian oligarch and rescue his American wife, all hell breaks loose...
