Keller is a regular guy, a solid citizen. He goes to the movies, watches the tube, browses the art galleries, and works diligently on his stamp collection. But every now and then a call from the breezily efficient Dot sends him off to kill a total stranger. He takes a plane, rents a car, finds a hotel room, and gets back before the body is cold. He's a real pro, cool and dispassionate and very good at what he does. Until one day when Dot breaks her own rule and books him for a hit in New York, his home base. She sends him to an art gallery opening, and the girl he gets lucky with steers him to an astrologer. He's a Gemini, his moon's in Taurus and he's got a murderer's thumb. Then the jobs start to go wrong. Targets die before he can draw a bead on them. The realization is slow in coming, but there's no getting around it - Somebody out there is trying to hit the hit man. Keller, God help him, has found his way on to somebody else's hit list.
