Once in the U.S. he joins a gang under Darky White where stealing, drugs and murder are part of the routine. Things aren't bad enough but he falls for the boss's girl and a complication is added.
After a major job, members of the gang go to Mexico and Michael is arrested. What happens in the prison and how he escapes will be left for the reader to learn.
Back in the U.S. and wanting to lay low, he's contacted by a rival gang leader to act as his bodyguard.
Michael feels betrayed by his friends from what happened in Mexico and retribution becomes one of his motives.
I disliked Michael as a character and didn't see any redeeming characteristics. It would be difficult to recommend this book other than it describes a slice of life of Irish gangs in Brooklyn and New York.
