Initially, the doctors had put her symptoms down to the stress of raising a family. Several months into therapy, however, a completely different personality emerged, as brazen as Chris Sizemore’s other self was demure. Thigpen and Cleckley dubbed this provocative self “Eve Black”, while the dominant yet quieter personality was “Eve White”. It was Eve Black who had tried to choke Chris Sizemore’s two-year-old daughter, leading her to seek psychiatric help for the first time.
While Eve White liked reading, Eve Black preferred to spend her days at the cinema and her evenings in nightclubs. In The Three Faces of Eve, Thigpen and Cleckley described their efforts to encourage the emergence and eventual dominance of “Jane”, a third, more capable personality.
