Doyle and the spiritualist William Thomas Stead (before the latter was lost in the sinking of the Titanic) were led to believe that Julius and Agnes Zancig had genuine psychic powers, and they claimed publicly that the Zancigs used telepathy. However, in 1924, the Zancigs confessed that their mind reading act had been a trick; they published the secret code and all other details of the trick method they had used under the title "Our Secrets!!" in a London newspaper.[77] Doyle also praised the psychic phenomena and spirit materializations that he believed had been produced by Eusapia Palladino and Mina Crandon, both of whom were also later exposed as frauds.[78]
