When a strange letter signed Thanatos -- the ancient Greek name for death -- lands on Irene Kelly's desk, the intrepid reporter doesn't think much of it; she gets crazy mail all the time. A less cryptic message is sent when a body turns up the next morning. As more letters roll in, the death toll mounts...and Irene fears that her mysterious pen pal has cast her in his own private Greek tragedy as Cassandra, the seer whom others refused to believe. It's the killer's dream to challenge Irene to follow his ancient blueprint for murder. It's his ultimate desire to make her face the inevitable -- that she is the next to die.
