The Wrath of God — Jack Higgins

A life of violence haunts 3 desperate men, whose attempts to escape their pasts only confirm their chosen way of life. Emmet Keogh is a trained assassin who can no longer remember how many people he has killed. Van Horne, a past priest, bank robber and murderer is running from the law...and himself. Janos, a businessman, hotel proprietor, and gunrunner is a mysterious man with an even more mysterious past. Survival is not only escaping the death around them, but the pasts they brought with them.
