Chain of Vengeance — William Beechcroft

A son swears a sacred oath of vengeance to his dying mother. He's a hitman for the Mafia, but his next string of killings will be strictly personal. The first victim is a night watchman in New York City, then a retired engineer near Baltimore, a Scranton jeweler, an Arizona real estate salesman, a small0time Hollywood agent, join the list. All five executed with a .22 slug in the head. Only one man sees the pattern - Dan Forrest, a reporter for a tabloid scandal sheet, has a hunch. Soon he's got the story of the year. But one false move and he'll be making news himself - on the obit page. Because now he's left his typewriter for a coast-to-coast race with the killer to find the final link in the Chain Of Vengeance.
