The Postcard Killers

NYPD detective Jacob Kanon is on a tour of Europe's most gorgeous cities. But the sights aren't what draw him - he sees each museum, each cathedral, and each café through the eyes of his daughter's' killer. Kanon's daughter 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.
