The Honeymoon Assignment (The Bowin Novels), by Lee Holz:

Well-written sequel that is solid enough to stand alone from the first story and loses nothing of the punch of the original, as the reader follows covert government agent and assassin, Tom Bowin, accompanied by his wife, Alice, on a new mission.
I’ve thoroughly enjoyed reading these intricately-plotted, cut-to-the-chase thrillers that put the reader right into the heat of the action from the very start of the story.
