Brice Kantor and Ben Castelano are both crime writers, but that's where the resemblance ends. Brice is a star, with an impatient publisher and no book. Ben is on the skids, with a manuscript ready and no publisher. When they bump into each other in a train station, Brice makes Ben a fantastic offer: half his huge advance in return for Ben's book. Only trouble is, Brice's ex-wife Lucie gets half his earnings. If Ben wants her share, Lucie must die.
