«Once a Crooked Man» by David McCallum

Sal, Max, and Enzo Bruschetti have spent their entire lives keeping a low profile. As their criminal empire as grown more diverse, they have relied on an increasingly complex web of financial arrangements to keep their business safe from prying eyes. Now wealthy and aging, they have decided to retire from crime. Right after they tie up a few loose ends…But when actor Harry Murphy inadvertently overhears the Bruschetti brothers plotting to turn several associates into “dead meat” he is stricken by conscience and decides he must intervene. After traveling to London to warm one of the intended victims, Harry is caught up in a shootout, forced to flee in a high speed chase, mistaken for a Bruschetti agent, and handed a suitcase filled with cash. Out of his depth and in over his head, Harry is picked up by the British authorities who want to use him to build a case against the mysterious Bruschettis.
