'K. T. McCall is a pseudonym for Audrey Armitage and Muriel Watkins.' The picture on the back of the novels was 'a model from the June Dally-Watkins Agency' (Source: Johnson-Woods, Pulp, p. 36).
On back cover Killer Orchid above photograph: 'Meet K. T. McCall. Blonde, beautiful and with brains - a combination that has taken K.T. into the front ranks of the world's highest paid women writers ... The prototype Buchanan could be in London, New York or New Guinea - but anywhere, he's all man and all K.T.'s.'
