Book ~ "Dear Irene" (1995) Jan Burke

From Goodreads ~ 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.

This is the third in the series of eleven (as of 2011). I read it years ago and am rereading the series.

This one was okay. Irene and Frank are now engaged and living together and expanding their family.

Irene is just getting back to work after the beating she had in the second book. Frank is very protective and its driving her crazy.

She starts getting cryptic letters giving her clues to murders. Working together with the police and other reporters, she goes down the path of solving the mystery.

The "whodunnit" was an interesting twist that came and ended quickly.
