Gregor Demarkian grew up in the Armenian-American enclave in Philadelphia known as Cavanaugh Street. Even though he left to go to college, and then went on to a storied career, he eventually returned to Cavanaugh Street after an early retirement. There he still retains some of the friends. Among them is Father Tibor Kasparian, probably the most genuinely gentle soul that Demarkian has ever met. When Father Tibor is then arrested on murder charges, it tears at the very foundation of Demarkian's world. While Gregor has very strict rules about for whom and under what conditions he will consult, all those rules go by the wayside. Demarkian is now a man possessed, and his one goal is to find out what really happened and who is really responsible for the murder Father Tibor is charged with.
