Cricket bag

Whilst playing in a charity cricket match in Tasmania, the Fifth Doctor made extensive use of his cricket bag. Its size and ordinary appearance gave him the ability to conceal a variety of equipment beyond that needed to play cricket. He was able to surreptitiously monitor the vampiric beings who had taken over Nyssa from the contents of the apparently innocuous, and usefully portable, contents of the bag. (PROSE: Goth Opera)
