Cousin Mervyn - S1.E18

Strange holes start appearing in Gordon’s garden. It seems that anything made of wood is prone to the attack. First it’s the rungs on Gordon’s ladder, then the coupling on his trike and trailer and even his front door! “Are you or have you ever been a woodworm?" is the question everyone wants to know of Andrew. "No" is the answer, but Andrew knows someone who is – his cousin Mervyn. Andrew has to tell Gordon what’s really going on.
