This is from the John Keller series, original publication date 1998, featuring an introspective killer-for-hire. It's a assembly of short stories/novellas that hang together on a common theme. (The Kirkus review asks "Is the result a novel or a cycle of stories?")
"Keller is your basic urban Lonely Guy.He makes a decent wage, lives in a nice apartment.Works the crossword puzzle. Watches a little TV. Until the phone rings and he packs a suitcase, gets on a plane, flies halfway across the country...and kills somebody. It's a living. But is it a life? Keller's not sure. He goes to a shrink, but it doesn't work out the way he planned. He gets a dog, he gets a girlfriend. He gets along."
And the icing on the cake: the unabridged audiobook can be added for $2.99.
In the rare case that you may not be familiar with Lawrence Block, he's probably one of the most influential writers in the genre over the last 40 years, on a par with Ed McBain, Donald Westlake, etc.. He's one of those rare authors who's managed to write several long-running successful series in slightly different ranges, and do so convincingly. My particular favorite is the Evan Tanner series, about a spy who never sleeps because of a brain injury.
