"Ed McBain" is one of the pen names of American author and screenwriter Salvatore Albert Lombino (1926-2005), who legally adopted the name Evan Hunter in 1952.
While successful and well known as Evan Hunter, he was even better known as Ed McBain, a name he used for most of his crime fiction, beginning in 1956.
He also used the pen names John Abbott, Curt Cannon, Hunt Collins, Ezra Hannon, Dean Hudson, Evan Hunter, and Richard Marsten.
Just about an average collection of novellas. King's story had an interesting premise: a man who didn't show up for work on 9/11 at the Towers lost all his friends in the bombing. Later, he starts to find things that belonged to the dead friends and no matter how many times he disposes them off, they find their way back to his house. The story was sufficiently creepy but the resolution was kind of plain and lame.
Mosley's novella was hardly anything to write home about. Archibald Lawless, the mysterious giant of a man hires a college student to do some research for him. Soon, the student discovers that Lawless's work straddles the line between legal and illegal. A plain vanilla story with no surprises in store.
Block's novella was probably the best of the three. It was about Keller, a contract killer, who for the first time in his life begins to question that how long he could keep on doing his kind of work. Although, the job Keller carried out in the story wasn't that interesting, but some dry wit and above-average writing kept the story moving along.
