The Castle Series 4

The Castle is a BBC Radio 4 comedy set in the Middle Ages and referencing modern life: in the words of its own introduction, "a comedy set in the filth, stench and grime of the Middle Ages, with some nice music". The exact timeframe of the series is not fixed; one episode specifies it to be in the early 12th century, yet another references Joan Of Arc. It is written by Kim Fuller and, from series 2, Paul Alexander with additional dialogue by Nick Doody, Matt Kirshen and Paul Dornan.
