Kanon's daughter, Kimmy, and her boyfriend were murdered while on vacation in Rome. Since then, young couples in Paris, Copenhagen, Frankfurt, and Stockholm have been found dead. Little connects the murders, other than a postcard to the local newspaper that precedes each new victim.
Now Kanon teams up with the Swedish reporter, Dessie Larsson, who has just received a postcard in Stockholm--and they think they know where the next victims will be. With relentless logic and unstoppable action, The Postcard Killers may be James Patterson's most vivid and compelling thriller yet.
