He seems to pressure others, Cal included. Skeffington paused and looked at him.He feels alone and scared of what will happen to him if he stays there any longer. Cal is affiliated with the terrorist organization and carries out acts of violence in their name, specifically the murder of Robert Morton. Crilly Crilly is Cal's key contact within the IRA, and is a dedicated follower of the terrorist movement. He is constantly looking for somewhere he might fit in. We see this through the examples of religious bigotry and also how relationships with friends and family can affect lives. Sin is another theme. We don't learn very much about Shamie as he is a peripheral character, central more to Cal's past than to his present. This makes him isolated because he has to bottle up everything he feels. Sexually frustrated, confused, etc. Crilly does not seem to have particularly noble or altruistic motives for his involvement, but seems rather to be a man of violence who has encountered a movement that conveniently gives him a place to direct it.
To make matters worse, Cal finds himself falling in love with the slain man's wife, Marcella. He loves his parents, hates the IRA after first working for themanger towards the local Protestants, and so on.
Cal lives with his father, Shamie, in Northern Ireland on a Protestant Estate and as they are Catholics, the only Catholics living there, there is conflict between Cal and Shamie and their neighbours.
Well, I got to a bit better how the ordinary Irishman lives from day to day. Shamie Shamie is Cal's father and was widowed whilst his son was only eight years old.
He meets a young women called Marcella who he has more in common than he thinks, which ultimately leads to his tragic fate. He wants to get punishment for what he has done so that he can be free of his sin.
Cal just wants a free Ireland but does not believe killing is the right way to get it. As his love for Marcella grows, so too does his guilt.
Sin is another theme. Cal does begin to feel a sense of guilt towards the end of the novel for what he has done, but this seems more self-serving than genuine, since it is prompted by a fear that it will be the end of his relationship with Marcella; he feels guilt because he took the life of her husband, but not because he committed the act of taking a life.
