—Book #1 in the series, THE CRIME FILES OF KATY GREEN

The novella that started it all!

It’s night, Sacramento, and single female drivers who break down on the side of Interstate-5 are relieved to see the highway safety CalTrans truck arrive to give assistance… until they realize that’s not what the 400-pound ex-boxer who gets out has in mind…

Such is the M.O. of serial killer, Jack Malenko, who preys on women in distress in full sight of passing traffic. Assigned to the notorious case are homicide detectives Katy Green and Johnny Cato, dubbed by the press as Sacramento’s “Green Hornet and Cato.” However, from the beginning of this case, the two detectives seem to continually be one step behind their huge killer… and each day that passes brings worse news and fresh victims.

How fast can they track down the predatory monster to save further lives, and if they do find him, can they save their own lives in the violent encounter?

With Introduction by John Palisano

and Interior Illustrations by Greg Chapman
