"What are you all so amused about?"

Ray smiled as she replied:

"We're arguing about dual personalities. Mr. Steell insists that there is no such thing. Mr. Reynolds agrees with him. He is wrong of course. I know of several well-authenticated cases, and the medical records are there to back me up."

"Exactly what do you mean by dual personality?" demanded the lawyer.

Ray returned to the attack, while Helen, amused, rose from the piano and went over to listen to the argument.

"I mean that a person we know well may suddenly cease being that person and assume a personality entirely different."

Mr. Steell laughed derisively.

"Does the patient change her or his skin?"

"No, the change is wholly mental. Although in fact, the new mental attitude does result in certain physical modifications. For instance, a person who in his normal condition may be most punctilious and neat in his dress is likely to become unkempt and slovenly in the new character he unconsciously assumes."

"Have you ever encountered any such dual personalities?"
