The ring of death

the long version

"Nothing could have prepared DCI Monika Paniatowski for this. It's not that the man's throat has been cut, or that he is naked, that shocks her - it's the way his corpse has been so carefully posed. Is the killer sending a message? If so, to whom? Saddled with a colleague she doesn't trust, and watched by an old enemy, Monika realises that whatever the murderer's message is, he will not stop killing until she understands."--Publisher.
