"The Lieutenant of Inishmore" is the follow up play which was written as a response to the 1993 Warrington bombings when two children were killed by the IRA. It is a dark comedy in which the insane leader of an INLA (Irish National Liberation Army) splinter group discovers that his best friend, a cat, has been killed. The play was produced Off-Broadway in February 2006 by the Atlantic Theater Company. It transferred to Broadway in May 2006 and received a 2006 Tony Award nomination for Best Play.
