I'm picking this one up with a little reservation as, in earlier books in the series, I've really struggled with the central character Annika Bengtzon. We'll see.
From the Blurb:
AN ACCIDENTAL DEATH?
Reporter Annika Bengtzon is working on the story of a devastating crime when she hears that a journalist investigating the same incident has been killed. It appears to be a hit-and-run accident.
A SERIES OF MURDERS
Several brutal killings follow - all linked by handwritten letters sent to the victims' relatives. When Annika unravels a connection with the story she's writing, she is thrown on to the trail of a deadly psychopath.
THE HUNT IS ON
Caught in a frenzied spiral of secrets and violence, Annika finds herself and her marriage at breaking point. Will her refusal to stop pursuing the truth eventually destroy her?
