Jonathan Frost

Jonathan Frost, along with his friends Jake Christie, Annie Wren, Sarah Tiller, Mark Hopethorne and Carl Richards, rented 11 Cardinal Road from a mysterious landlord in 1997. All six disappeared.

The group took a series of polaroid photos as they moved into the property. These, along with their personal possessions, were later found by the Twelfth Doctor and Harry, boxed up in the basement of the house. The photos showed their ill-fated escape from an infestation of lice. (TV: Knock Knock)
