In the novel At Bertram's Hotel, Chadminster is a cathedral town. Canon Pennyfather is a canon at the cathedral there and resides at the cathedral close. Inspector Campbell and Chief-Inspector Davy went to Chadminster to interview the canon after he had been found knocked unconscious by the side of a road. Of interest to them was the fact that a woman who resides in Chadminster and who knows the canon by sight thought she saw the canon getting on to the train during the time the train was being robbed. The expedition of the policemen to Chadminster was in the end largely unfruitful as the canon could tell them very little.
