E-mail from Michael Roll to Denise Iredell (January 23, 2005): Survival or Oblivion? Let's Give People a Choice.

In his e-mail, Michael Roll writes:
”You are one of the few people left alive who witnessed Helen Duncan's mediumship that gave such hope and comfort to people who had lost loved ones, especially as she was operating not long after the terrible slaughter of the First World War. Please be kind enough to put in writing to me what you said on the phone yesterday - that the red light that was used at a Helen Duncan experiment was bright enough to see all the people in the room including the expressions on their faces, that two "dead" people you knew very well fully materialised, a close family friend and a girl you were at school with.”
