I have read a previous Lars Kepler (husband-and-wife Alexander and Alexandra Ahndoril's team pseudonym) installment in the " Joona Linna series," The Sandman, and it was very dark. I guess I forgot just how dark until I embarked on this very Scandinavian noir (#7 in the series) that takes place several years after the events in that book. In fact, the villain of The Sandman supposedly died but reappears here, hence the title. When someone starts killing some of Europe's most heinous criminals, nobody is particularly worried about catching the killer, except that two of the murders have connections to Joona Linna, who becomes convinced that they are being committed by the man that he thought was dead, serial killer Jurek Walter. His partner, Saga Bauer, is the one who shot Walter and she thinks Joona is totally off base, but there are too many similarities to the earlier deaths by Walter, and Joona goes on the hunt to prove he's right and trap his enemy once again. 

Booklist says, "Kepler combines explosive action with masterfully developed tension." Publishers Weekly agrees that fans of this genre and/or series "won't want to miss this one."
