A killer leaves a mysterious trail of death with Buddhist overtones, and FBI Agent Cain Shepherd, a practicing Buddhist, is the FBI’s last hope to understand the subtle clues, and stop a murderer before it’s too late…

 

Predators are dying by their own methods as FBI Agent Cain Shepherd decodes crime scenes of righteous retribution. Can he stop a spiritually-corrupted killer who views murder as the path to enlightenment before he claims the next victim?
