In 1919, the magician P. T. Selbit staged a séance at his flat in Bloomsbury, which Doyle attended. Although some later claimed that Doyle had endorsed the apparent instances of clairvoyance at that séance as genuine,[83][84] a contemporaneous report by the Sunday Express quoted Doyle as saying "I should have to see it again before passing a definite opinion on it" and "I have my doubts about the whole thing".[85] In 1920, Doyle and the noted sceptic Joseph McCabe held a public debate at Queen's Hall in London, with Doyle taking the position that the claims of spiritualism were true.
