Crossover Cover: Kill Fee

N.Y.P.D. Lieutenant James Murtaugh attempts to apprehend a contract killer named Pluto, who picks his targets first and seeks money from people who stand to profit by their deaths only after the hit. Murtaugh went on to appear in Paul’s Marian Larch novels. Win included Paul's novel The Fourth Wall in Volume 2 due to references to Archie Goodwin and Dr. Vollmer from the Nero Wolfe series, and noted that some of the characters from that novel went on to appear in the Larch series.
