This dark yet funny story is told by a man who for two months has been a patient at a New York City mental ward. Having suffered a breakdown, he now finds himself caught between two worlds: the world of the ward, where abnormality and an odd sort of freedom reign, and the outside world, where convention and restrictive behavior rule. Finally on his way to becoming reasonably "normal" again, he is granted a “solo pass”, which allows him to leave the ward for several hours and visit the city.
Narrated from the perspective of an American-born contract killer based in London, Calling Mr. King takes us into the mind and life of a man who is growing both increasingly cautious and distracted as he travels from job to job, city to city. Though long considered a first-rate, consistently reliable marksman with a cool, unshakable personality, he appears to be undergoing a severe change of character and focus, taking an interest as never before in the world beyond his targets.
