Columbo: The Conspirators on AllMovie

The Conspirators was one of four Columbo feature-length TV specials irregularly scheduled during the 1977-1978 TV season. The titular conspirators are Irish political terrorists, funded by Americans. Clive Revill is an Irish poet who murders an arms dealer (Bernard Behrens) while the poet is gunrunning to his compatriots in Ireland. The murderer is certain that he's thoroughly covered her tracks--until Lt. Columbo (Peter Falk) shambles onto the scene. Columbo: The Conspirators was filmed at a time when Peter Falk was insisting that he would hang up the lieutenant's raincoat for good; no way.
