This book examines the different forms of violence found in three plays by Irish playwright Martin McDonagh: The Beauty Queen of Leenane (1996), The Lieutenant of Inishmore (2001) and The Pillowman (2003). It can be seen that the writer works on the theme of violence constantly and recurrently, although the treatment of this theme varies and differs from one play to the next. The aim is to prove, through critical analysis, that McDonagh's writings are not a censure of Irish society, as suggested in various academic works; his plays are, in fact, a reflection on globalised society and the human beings who inhabit this global community.
