Mrs. Clarkson is the wife of Sanders-Hardiman Expedition photographer Peter Clarkson. She is first told of her husband's curse from a clairvoyant stage act by Ragdalam the Fakir and Madame Yamilah, though she is sceptical of it. After this she is informed of it by a more trustworthy source. She is seen later visiting Peter in hospital while he was in the coma.
