Doyle defended Hope, but further evidence of trickery was obtained from other researchers.[91] Doyle threatened to have Price evicted from the National Laboratory of Psychical Research and predicted that, if he persisted in writing what he called "sewage" about spiritualists, he would meet the same fate as Harry Houdini.[92] Price wrote: "Arthur Conan Doyle and his friends abused me for years for exposing Hope."[93] In response to the exposure of frauds that had been perpetrated by Hope and other spiritualists, Doyle led 84 members of the Society for Psychical Research to resign in protest from the society on the ground that they believed it was opposed to spiritualism.[94]
