I'm Eddie Collins, a CSI. This is the story of how I saw a dead man die.

I was finishing up at a sudden death in an old house, waiting for the body snatchers to arrive, when I heard a noise from the cellar.

I had time to kill, so I went to investigate.

Turns out I wasn't the only one with killing on his mind.

To find out what's in that cellar, buy The Lock today.

Andrew Barrett is the best-selling author of the Eddie Collins Series. The Lock will appeal to fans of authors like Ian Rankin, Robert Bryndza and Kathy Reichs.
