—Book #3 in the series, THE CRIME FILES OF KATY GREEN

Young Billy Williams has been elevated to status of Shepherd of the Flock—leader of a zealous religious cult—and granted gift of the Deathflash, the ability to see the soul as it departs its mortal form at demise.

Billy is also given an ancient knife-like talon and “commanded to do the Lord’s work,” which he does fanatically, slaying drug addicts in San Francisco who are poisoning their bodies with heroin...

Retired police detectives Katy Green and Johnny Cato find themselves drawn into the grim case of the murdered underclass, whom no one seems to care about until the brother of a victim comes forward with his incredible suspicions…

So begins a journey of addiction, tracking a killer through the dope dens and seedy rehab houses of the Tenderloin district. But as more time passes, junkies begin to die faster and faster, for Billy Williams has given himself entirely to his own addiction: the rush of viewing the Deathflash.
