From first impressions, Michael Collins is a stereotypical college professor, but from another standpoint, he is a Vietnam veteran, a highly trained intelligence officer, angel to some, slayer to others. He is a regular killing machine.

Collins, otherwise known as Cain, trained several skilled men in Vietnam War tactics, teaching and leading them on missions to kill the enemy and rescue any comrades, or just kill the enemy if needed. It was inevitable that this group of men would form a bond of brotherhood. After the war ended, when they returned to their lives at home, some kept in touch, some chose to forget.

Cain's commanding officer and close family friend contacts him and asks him to hunt down one of his own men. Seneca was always a little different from the other men on the team. Whereas they learned to kill to perform their duties, Seneca always loved the act of killing. The more he killed, the happier he was. Cain was the original killer, the best of his group, able to install fear in all who crossed his path. He didn't enjoy killing, he just didn't feel anything while doing so. Even Seneca is afraid of Cain, a man who never missed and never showed emotion while killing people.

Now Seneca has gone rogue and killed one of his team members and the tally is growing. Using his information network, Cain stays right behind Seneca's bloody path. Cain learns that Seneca is on someone's payroll, ready to execute a grand scheme, which will result in a high-profile death. A military person has a set of rules, loyalty to the United States the highest of priorities. Even a soldier's bond to his teammate is not enough when the line is crossed.

Tom Wallace captures the essence of what some soldiers experienced in the Vietnam War; the psychological baggage that must have tortured so many men upon their return. Wallace superbly presents Michael Collins (Cain), who has been able to compartmentalize that vicious part of his life and assume more steadfast duties as a professor, while secretly wondering if he still has what it takes. HEIRS OF CAIN is graphic, chilling, exciting and thoroughly worth the time to read. For those who are daring enough to step out of their typical reading genre, I invite you to check out HEIRS OF CAIN. For all others who would regularly read this genre, enjoy!
