Safety Catch is a sitcom on BBC Radio 4 created by Laurence Howarth and written by Howarth and John Finnemore. The series was first broadcast in 2007. It is about Simon McGrath (played by Darren Boyd), a man who works in a job that he does not like – the arms trade. The show mocks issues of morality, although Howarth claims that the show is not satirical. Because of the subject matter and the light-hearted way it is treated, the series is one of Radio 4's most controversial.
