Carl Lynwood Sargent (11 December 1952 – 12 September 2018)[1][2][3][4] was a British parapsychologist and author of several roleplaying game-based products and novels, who used the pen name Keith Martin to write Fighting Fantasy gamebooks.
The book received a positive review in the New Scientist by John Beloff who described it as "an introduction to parapsychology that one can put into the hands of an inquiring student without embarrassment.
"[7] In their book Sargent and Eysenck argued that the experiments of William Crookes with the medium Daniel Dunglas Home were evidence for supernatural powers.
Susan Blackmore, who visited Sargent's laboratory in Cambridge, detected several errors and failures to follow the protocol during an experiment.
Psychologists reading Daryl Bem's review in Psychological Bulletin would "not have a clue that serious doubt had been cast on more than a quarter of the studies involved" Sargent and Chuck Honortons.
Sargent authored various Fighting Fantasy gamebooks and novels for Games Workshop from 1988 to 1995, some under the pseudonym Keith Martin.
