Conan Doyle spirit voice from beyond
From The Arthur Conan Doyle Encyclopedia
On 28 April 1934, a séance held by Noah Zerdin at the Aeolian Hall, New Bond Street, attracted a capacity audience of 560 people, with many turned away. It was the first large gathering of its kind to be recorded, and Conan Doyle was one of 44 people heard speaking from the 'other side'. 
"God, thanks God, the great divine help each quality, and also, take care of my boys and my good wife Jean, God help our movement forward, let beyond [...], the onward and forward is the wish of Arthur Conan Doyle."
