THE IMMORTAL Carnage

While Aaron and Alexis enjoy their honeymoon on Aaron's private island resort, three of Los Angele's superrich, one of whom is the mayor of Los Angeles, are murdered just days apart, each in a different manner. Aaron suspects the killings are not random unrelated events and upon his return home convinces Captain Frank McGarry of the LAPD to let him investigate.
Soon Aaron discovers that all three men were childhood friends who grew up in the same small town in Iowa. During Aaron's investigation, another murder occurs. The wife of one of the victims is killed. She, too, was one of the group of small town kids who grew up together. Who is murdering these childhood friends and why?
Aaron's investigation takes him from the world of the southern California super rich to a small town in Iowa, a town where an old secret had remained hidden for many years.
