Last summer, J. Mark Bertrand's critically-acclaimed crime novel Back on Murder launched a series about Houston homicide detective Roland March. Now the next book in the series, Pattern of Wounds, which Publishers Weekly describes as "gritty and chilling," is available for purchase. The third book, Nothing to Hide, will release in the summer of 2012.

In Pattern of Wounds, it's Christmas in Houston, and homicide detective Roland March is on the hunt for a killer. A young woman's brutal stabbing in an affluent neighborhood bears all the hallmarks of a serial murder. The only problem is that March sent the murderer to prison ten years ago. Is it a copycat -- or did March convict the wrong man?

Alienated from his colleagues and with a growing rift in his marriage, March receives messages from the killer. The bodies pile up, the pressure builds, and the violence reaches too close to home. Up against an unfathomable evil, March struggles against the clock to understand the hidden message in the pattern of wounds.

J. Mark Bertrand lived in Houston, where the series is set, for fifteen years, earning an MFA in Creative Writing at the University of Houston. But after one hurricane too many he left for South Dakota. Mark has been arrested for a crime he didn't commit, was the foreman of one hung jury and served on another that acquitted Vinnie Jones of assault. In 1972, he won an honorable mention in a child modeling contest, but pursued writing instead.
