"Obsessions and phobias have their origin, according to Freud, in sexual life. The obsession represents a compensation or substitute for an unbearable sexual idea and takes its place in consciousness. In normal sexual life, no neurosis is possible, say the Freudists. Sex is the strongest impulse, yet subject to the greatest repression, and hence the weakest point of our cultural development. Hysteria arises through the conflict between libido and sex-repression. Often sex-wishes may be consciously rejected but unconsciously accepted. So when they are understood every insane utterance has a reason. There is really method in madness.

"When hysteria in a wife gains her the attention of an otherwise inattentive husband it fills, from the standpoint of her deeper longing, an important place, and, in a sense, may be said to be desirable. The great point about the psychanalytic method, as discovered by Breuer and Freud, is that certain symptoms of hysteria disappear when the hidden causes are brought to light and the repressed desires are gratified."

"How does that apply to Mrs. Cranston?" I queried.

"Mrs. Cranston," he replied, "is suffering from what the psychanalysts call a psychic trauma—a soul-wound, as it were. It is the neglect, in this case, of her husband, whom she deeply loves. That, in itself, is sufficient to explain her experience wandering through the country. It was the region which she associated with her first love-affair, as she told us. The wave of recollection that swept over her engulfed her mind. In other words, reason could no longer dominate the cravings for a love so long suppressed. Then, when she saw, or imagined she saw, one who looked like her lover the strain was too great."

It was the middle of the afternoon when we reached the laboratory. Kennedy at once set to work studying the drops of tonic which had been absorbed in the handkerchief. As Kennedy worked, I began thinking over again of what we had seen at the Belleclaire Sanatorium. Somehow or other, I could not get out of my mind the recollection of the man rolled in the blanket and trussed up as helpless as a mummy. I wondered whether that alone was sufficient to account for the quickness with which he had been pacified. Then I recalled Mrs. Cranston's remark about her mental alertness and physical weakness. Had it anything to do with the "tonic"?

"Suppose, while I am waiting," I finally suggested to Craig, "I try to find out what Cranston does with his time since his wife has been shut off from the world."

"That's a very good idea," acquiesced Kennedy. "Don't take too long, however, for I may strike something important here any minute."

After several inquiries over the telephone, I found that since his wife had been in Montrose Cranston had closed his apartment and was living at one of his clubs. Having two or three friends who were members, I did not hesitate to drop around.

Unfortunately, none of my friends happened to be there, and I was forced, finally, to ask for Cranston himself, although all that I really wanted to know was whether he was there or not. One of the clerks told me that he had been in, but had left in a taxicab only a short time before.

As there was a cab-stand outside the club, I determined to make an inquiry and perhaps discover the driver who had had him. The starter knew him, and when I said that it was very important business on which I wanted to see him he motioned to a driver who had just pulled up.
