Long considered cool, distant, and absolutely reliable, an American-born hit man, working throughout Europe, grows increasingly distracted and begins to develop an unexpected passion for architecture and art while engaged in his deadly profession. Although he welcomes this energizing break from his routine, he comes to realize that it is an unwise trajectory for a man in his business, particularly when he is sent on the most difficult job of his career.<br>   Set in London, Paris, New York, and Barcelona, <i>Calling Mr. King </i>is at once a colorful suspense tale, laced with dark humor, and a psychological self-portrait of a character who is attempting, against the odds, to become someone else.
