The third of the Darian Richards books by Tony Cavanaugh is due out later in February.

From the Blurb:

One man pushed Darian Richards to the edge. The man he couldn't catch. The Train Rider.

As Victoria's top homicide investigator, Darian Richards spent years catching killers. The crimes of passion, of anger, of revenge ... they were easy. It was the monsters who were hard.
