O'CONNOR.

"H-m," remarked Kennedy; "not strange for the Missing Persons Squad to be baffled - at least, at this case."

"Then you know of our daughter's strange - er - departure?" asked Mr. Gilbert, eagerly scanning Kennedy's face and using a euphemism that would fall less harshly on his wife's ears than the truth.

"Indeed, yes," nodded Craig with marked sympathy: "that is, I have read most of what the papers have said. Let me introduce my friend, Mr. Jameson. You recall we were discussing the Georgette Gilbert case this morning, Walter?"

I did, and perhaps before I proceed further with the story I should quote at least the important parts of the article in the morning Star which had occasioned the discussion. The article had been headed, "When Personalities Are Lost," and with the Gilbert case as a text many instances had been cited which had later been solved by the return of the memory of the sufferer. In part the article had said:

Mysterious disappearances, such as that of Georgette Gilbert, have alarmed the public and baffled the police before this, disappearances that in their suddenness, apparent lack of purpose, and inexplicability, have had much in common with the case of Miss Gilbert.

Leaving out of account the class of disappearances such as embezzlers, blackmailers, and other criminals, there is still a large number of recorded cases where the subjects have dropped out of sight without apparent cause or reason and have left behind them untarnished reputations. Of these a small percentage are found to have met with violence; others have been victims of a suicidal mania ; and sooner or later a clue has come to light, for the dead are often easier to find than the living, Of the remaining small proportion there are on record a number of carefully authenticated cases where the subjects have been the victims of a sudden and complete loss of memory.

This dislocation of memory is a variety of aphasia known as amnesia, and when the memory is recurrently lost and restored it is an "alternating personality." The psychical researchers and psychologists have reported many cases of alternating personality. Studious efforts are being made to understand and to explain the strange type of mental phenomena exhibited in these cases, but no one has as yet given a final, clear, and comprehensive explanation of them. Such cases are by no means always connected with disappearances, but the variety known as the ambulatory type, where the patient suddenly loses all knowledge of his own identity and of his past and takes himself off, leaving no trace or clue, is the variety which the present case calls to popular attention.

Then followed a list of a dozen or so interesting cases of persons who had vanished completely and had, some several days and some even years later, suddenly "awakened" to their first personality, returned, and taken up the thread of that personality where it had been broken.

To Kennedy's inquiry I was about to reply that I recalled the conversation distinctly, when Mr. Gilbert shot an inquiring glance from beneath his bushy eyebrows, quickly shifting from my face to Kennedy's, and asked, "And what was your conclusion - what do you think of the case? Is it aphasia or amnesia, or whatever the doctors call it, and do you think she is wandering about somewhere unable to recover her real personality?"

"I should like to have all the facts at first hand before venturing an opinion," Craig replied with precisely that shade of hesitancy that might reassure the anxious father and mother, without raising a false hope.

Mr. and Mrs. Gilbert exchanged glances, the purport of which was that she desired him to tell the story.

"It was day before yesterday," began Mr. Gilbert, gently touching his wife's trembling hand that sought his arm as he began rehearsing the tragedy that had cast its shadow across their lives, "Thursday, that Georgette - er - since we have heard of Georgette." His voice faltered a bit, but he proceeded: "As you know, she was last seen walking on Fifth Avenue. The police have traced her since she left home that morning. It is known that she went first to the public library, then that she stopped at a department store on the avenue, where she made a small purchase which she had charged to our family account, and finally that she went to a large book-store. Then - that is the last."

Mrs. Gilbert sighed, and buried her face in a lace handkerchief as her shoulders shook convulsively.

"Yes, I have read that," repeated Kennedy gently, though with manifest eagerness to get down to facts that might prove more illuminating. "I think I need hardly impress upon you the advantage of complete frankness, the fact that anything you may tell me is of a much more confidential nature than if it were told to the police. Er-r, had Miss Gilbert any - love affair, any trouble of such a nature that it might have preyed on her mind?"

Kennedy's tactful manner seemed to reassure both the father and the mother, who exchanged another glance.

"Although we have said no to the reporters," Mrs. Gilbert replied bravely in answer to the nod of approval from her husband, and much as if she herself were making a confession for them both, "I fear that Georgette had had a love affair. No doubt you have heard hints of Dudley Lawton's name in connection with the case? I can't imagine how they could have leaked out, for I should have said that that old affair had long since been forgotten even by the society gossips. The fact is that shortly after Georgette 'came out,' Dudley Lawton, who is quite on the road to becoming one of the rather notorious members of the younger set, began to pay her marked attentions. He is a fascinating, romantic sort of fellow, one that, I imagine, possesses much attraction for a girl who has been brought up as simply as Georgette was, and who has absorbed a surreptitious diet of modern literature such as we now know Georgette did. I suppose you have seen portraits of Georgette in the newspapers and know what a dreamy and artistic nature her face indicates?"

Kennedy nodded. It is, of course, one of the cardinal tenets of journalism that all women are beautiful, but even the coarse screen of the ordinary newspaper half-tone had not been able to conceal the rather exceptional beauty of Miss Georgette Gilbert. If it had, all the shortcomings of the newspaper photographic art would have been quickly glossed over by the almost ardent descriptions by those ladies of the press who come along about the second day after an event of this kind with signed articles analysing the character and motives, the life and gowns of the latest actors in the front-page stories.

"Naturally both my husband and myself opposed his attentions from the first. It was a hard struggle, for Georgette, of course, assumed the much-injured air of some of the heroines of her favourite novels. But I, at least, believed that we had won and that Georgette finally was brought to respect and, I hoped, understand our wishes in the matter. I believe so yet. Mr. Gilbert in a roundabout way came to an understanding with old Mr. Dudley Lawton, who possesses a great influence over his son, and - well, Dudley Lawton seemed to have passed out of Georgette's life. I believed so then, at least, and I see no reason for not believing so yet. I feel that you ought to know this, but really I don't think it is right to say that Georgette had a love affair. I should rather say that she had had a love affair, but that it had been forgotten, perhaps a year ago."

Mrs. Gilbert paused again, and it was evident that though she was concealing nothing she was measuring her words carefully in order not to give a false impression.

"What does Dudley Lawton say about the newspapers bringing his name into the case?" asked Kennedy, addressing Mr. Gilbert.

"Nothing," replied he. "He denies that he has even spoken to her for nearly a year. Apparently he has no interest in the case. And yet I cannot quite believe that Lawton is as uninterested as he seems. I know that he has often spoken about her to members of the Cosmos Club where he lives, and that he reads practically everything that the newspapers print about the case."

"But you have no reason to think that there has ever been any secret communication between them? Miss Georgette left no letters or anything that would indicate that her former infatuation survived?"

"None whatever," repeated Mr. Gilbert emphatically. "We have gone over her personal effects very carefully, and I can't say they furnish a clue. In fact, there were very few letters. She rarely kept a letter. Whether it was merely from habit or for some purpose, I can't say."

"Besides her liking for Dudley Lawton and her rather romantic nature, there are no other things in her life that would cause a desire for freedom?" asked Kennedy, much as a doctor might test the nerves of a patient. "She had no hobbies?"

"Beyond the reading of some books which her mother and I did not altogether approve of, I should say no - no hobbies."

"So far, I suppose, it is true that neither you nor the police have received even a hint as to where she went after leaving the book-store?"

"Not a hint. She dropped out as completely as if the earth had swallowed her."

"Mrs. Gilbert," said Kennedy, as our visitors rose to go, "you may rest assured that if it is humanly possible to find your daughter I shall leave no stone unturned until I have probed to the bottom of this mystery. I have seldom had a case that hung on more slender threads, yet if I can weave other threads to support it I feel that we shall soon find that the mystery is not so baffling as the Missing Persons Squad has found it so far."

Scarcely had the Gilberts left when Kennedy put on his hat, remarking: "We'll at least get our walk, if not the show. Let's stroll around to the Cosmos Club. Perhaps we may catch Lawton in."

Luckily we chanced to find him there in the reading-room. Lawton was, as Mrs. Gilbert had said, a type that is common enough in New York and is very fascinating to many girls. In fact, he was one of those fellows whose sins are readily forgiven because they are always interesting. Not a few men secretly admire though publicly execrate the Lawton type.

I say we chanced to find him in. That was about all we found. Our interview was most unsatisfactory. For my part, I could not determine whether he was merely anxious to avoid any notoriety in connection with the case or whether he was concealing something that might compromise himself.

"Really, gentlemen," he drawled, puffing languidly on a cigarette and turning slowly toward the window to watch the passing throng under the lights of the avenue, "really I don't see how I can be of any assistance. You see, except for a mere passing acquaintance Miss Gilbert and I had drifted entirely apart - entirely apart - owing to circumstances over which I, at least, had no control."

"I thought perhaps you might have heard from her or about her, through some mutual friend," remarked Kennedy, carefully concealing under his nonchalance what I knew was working in his mind - a belief that, after all, the old attachment had not been so dead as the Gilberts had fancied.

"No, not a breath, either before this sad occurrence or, of course, after. Believe me, if I could add one fact that would simplify the search for Georgette - ah, Miss Gilbert - ah - I would do so in a moment," replied Lawton quickly, as if desirous of getting rid of us as soon as possible. Then perhaps as if regretting the brusqueness with which he had tried to end the interview, he added, "Don't misunderstand me. The moment you have discovered anything that points to her whereabouts, let me know immediately. You can count on me - provided you don't get me into the papers. Good-night, gentlemen. I wish you the best of success."

"Do you think he could have kept up the acquaintance secretly?" I asked Craig as we walked up the avenue after this baffling interview. "Could he have cast her off when he found that in spite of her parents' protests she was still in his power?"

"It's impossible to say what a man of Dudley Lawton's type could do," mused Kennedy, "for the simple reason that he himself doesn't know until he has to do it. Until we have more facts, anything is both possible and probable."

There was nothing more that could be done that night, though after our walk we sat up for an hour or two discussing probabilities. It did not take me long to reach the end of my imagination and give up the case, but Kennedy continued to revolve the matter in his mind, looking at it from every angle and calling upon all the vast store of information that he had treasured up in that marvellous brain of his, ready to be called on almost as if his mind were card-indexed.

Murders, suicides, robberies, and burglaries are, after all, pretty easily explained," he remarked, after a long period of silence on my part, "but the sudden disappearance of people out of the crowded city into nowhere is something that is much harder to explain. And it isn't so difficult to disappear as some people imagine, either. You remember the case of the celebrated Arctic explorer whose picture had been published scores of times in every illustrated paper. He had no trouble in disappearing and then reappearing later, when he got ready.

"Yet experience has taught me that there is always a reason for disappearances. It is our next duty to discover that reason. Still, it won't do to say that disappearances are not mysterious. Disappearances except for money troubles are all mysterious. The first thing in such a case is to discover whether the person has any hobbies or habits or fads. That is what I tried to find out from the Gilberts. I can't tell yet whether I succeeded."

Kennedy took a pencil and hastily jotted down something on a piece of paper which he tossed over to me. It read: 1.Love, family trouble. 2.A romantic disposition. 3.Temporary insanity, self-destruction. 4.Criminal assault. 5.Aphasia. 6.Kidnapping.

"Those are the reasons why people disappear, eliminating criminals and those who have financial difficulties. Dream on that and see if you can work out the answer in your subliminal consciousness. Good-night."

Needless to say, I was no further advanced in the morning than at midnight, but Kennedy seemed to have evolved at least a tentative programme. It started with a visit to the public library, where he carefully went over the ground already gone over by the police. Finding nothing, he concluded that Miss Gilbert had not found what she wanted at the library and had continued the quest, even as he was continuing the quest of herself.

His next step was to visit the department-store. The purchase had been an inconsequential affair of half a dozen handkerchiefs, to be sent home. This certainly did not look like a premeditated disappearance; but Craig was proceeding on the assumption that this purchase indicated nothing except that there had been a sale of handkerchiefs which had caught her eye. Having stopped at the library first and a book-shop afterward, he assumed that she had also visited the book-department of the store. But here again nobody seemed to recall her or that she had asked for anything in particular.

Our last hope was the book-shop. We paused for a moment to look at the display in the window, but only for a moment, for Craig quickly pulled me along inside. In the window was a display of books bearing the sign:
