Devlin is an Irishman. In his youth he was a terrorist but now he is a famous writer and, officially, a supporter of an American society proposing to help the victims of terrorism. Actually he is buying from Pauley weapons for the terrorists. Devlin kills him because he thinks he has been betrayed. Lt. Columbo is responsible for the inquiry and becomes friendly with Devlin, but it is very dangerous to be familiar with Lt. Columbo when you are a murderer.
