He didn't have to be told who the third was. Maureen. He'd all but forgotten her. It was the doctor's responsibility, but he didn't feel that way.

"She's not causing trouble," emphasized Cameron. "Daily she is growing more feminine and we'd have positive proof of it except that we've taken steps."

"Confinement?"

"No, except the solitude of her mind. Hypnotics. We tell her she's getting the regular injections and it's these which cause her to want to be left alone."

It was more stringent than he cared for but he didn't have a better suggestion. "How long can she continue on hypnotics?"

"Depends. The reaction varies with the person. She can tolerate quite a bit more."
