Conversation so far:
Who is Eileen Garrett?
On 7 October 1930 it was claimed by spiritualists that Eileen J.
Garrett made contact with the spirit of Herbert Carmichael Irwin.

Question: Did HArry try to prove Eilleen was a fake?
Self-contained rewrite: Did Harry try to prove Eileen Garrett was a fake and did not make contact with the spirit of Herbert Carmichael Irwin?
