Six months have elapsed. Summer-time has come again.

The last parting is over. Prolonged by my care, the days of my mother’s life have come to their end. She has died in my arms: her last words have been spoken to me, her last look on earth has been mine. I am now, in the saddest and plainest meaning of the words, alone in the world.

The affliction which has befallen me has left certain duties to be performed that require my presence in London. My house is let; I am staying at a hotel. My friend, Sir James (also in London on business), has rooms near mine. We breakfast and dine together in my sitting-room. For the moment solitude is dreadful to me, and yet I cannot go into society; I shrink from persons who are mere acquaintances. At Sir James’s suggestion, however, one visitor at the hotel has been asked to dine with us, who claims distinction as no ordinary guest. The physician who first warned me of the critical state of my mother’s health is anxious to hear what I can tell him of her last moments. His time is too precious to be wasted in the earlier hours of the day, and he joins us at the dinner-table when his patients leave him free to visit his friends.

The dinner is nearly at an end. I have made the effort to preserve my self-control; and in few words have told the simple story of my mother’s last peaceful days on earth. The conversation turns next on topics of little interest to me: my mind rests after the effort that it has made; my observation is left free to exert itself as usual.

Little by little, while the talk goes on, I observe something in the conduct of the celebrated physician which first puzzles me, and then arouses my suspicion of some motive for his presence which has not been acknowledged, and in which I am concerned.

Over and over again I discover that his eyes are resting on me with a furtive interest and attention which he seems anxious to conceal. Over and over again I notice that he contrives to divert the conversation from general topics, and to lure me into talking of myself; and, stranger still (unless I am quite mistaken), Sir James understands and encourages him. Under various pretenses I am questioned about what I have suffered in the past, and what plans of life I have formed for the future. Among other subjects of personal interest to me, the subject of supernatural appearances is introduced. I am asked if I believe in occult spiritual sympathies, and in ghostly apparitions of dead or distant persons. I am dexterously led into hinting that my views on this difficult and debatable question are in some degree influenced by experiences of my own. Hints, however, are not enough to satisfy the doctor’s innocent curiosity; he tries to induce me to relate in detail what I have myself seen and felt. But by this time I am on my guard; I make excuses; I steadily abstain from taking my friend into my confidence. It is more and more plain to me that I am being made the subject of an experiment, in which Sir James and the physician are equally interested. Outwardly assuming to be guiltless of any suspicion of what is going on, I inwardly determine to discover the true motive for the doctor’s presence that evening, and for the part that Sir James has taken in inviting him to be my guest.

Events favor my purpose soon after the dessert has been placed on the table.

The waiter enters the room with a letter for me, and announces that the bearer waits to know if there is any answer. I open the envelope, and find inside a few lines from my lawyers, announcing the completion of some formal matter of business. I at once seize the opportunity that is offered to me. Instead of sending a verbal message downstairs, I make my apologies, and use the letter as a pretext for leaving the room.

Dismissing the messenger who waits below, I return to the corridor in which my rooms are situated, and softly open the door of my bed-chamber. A second door communicates with the sitting-room, and has a ventilator in the upper part of it. I have only to stand under the ventilator, and every word of the conversation between Sir James and the physician reaches my ears.

“Then you think I am right?” are the first words I hear, in Sir James’s voice.

“Quite right,” the doctor answers.

“I have done my best to make him change his dull way of life,” Sir James proceeds. “I have asked him to pay a visit to my house in Scotland; I have proposed traveling with him on the Continent; I have offered to take him with me on my next voyage in the yacht. He has but one answer — he simply says No to everything that I can suggest. You have heard from his own lips that he has no definite plans for the future. What is to become of him? What had we better do?”

“It is not easy to say,” I hear the physician reply. “To speak plainly, the man’s nervous system is seriously deranged. I noticed something strange in him when he first came to consult me about his mother’s health. The mischief has not been caused entirely by the affliction of her death. In my belief, his mind has been — what shall I say? — unhinged, for some time past. He is a very reserved person. I suspect he has been oppressed by anxieties which he has kept secret from every one. At his age, the unacknowledged troubles of life are generally troubles caused by women. It is in his temperament to take the romantic view of love; and some matter-of-fact woman of the present day may have bitterly disappointed him. Whatever may be the cause, the effect is plain — his nerves have broken down, and his brain is necessarily affected by whatever affects his nerves. I have known men in his condition who have ended badly. He may drift into insane delusions, if his present course of life is not altered. Did you hear what he said when we talked about ghosts?”

“Sheer nonsense!” Sir James remarks.

“Sheer delusion would be the more correct form of expression,” the doctor rejoins. “And other delusions may grow out of it at any moment.”

“What is to be done?” persists Sir James. “I may really say for myself, doctor, that I feel a fatherly interest in the poor fellow. His mother was one of my oldest and dearest friends, and he has inherited many of her engaging and endearing qualities. I hope you don’t think the case is bad enough to be a case for restraint?”

“Certainly not — as yet,” answers the doctor. “So far there is no positive brain disease; and there is accordingly no sort of reason for placing him under restraint. It is essentially a difficult and a doubtful case. Have him privately looked after by a competent person, and thwart him in nothing, if you can possibly help it. The merest trifle may excite his suspicions; and if that happens, we lose all control over him.”

“You don’t think he suspects us already, do you, doctor?”

“I hope not. I saw him once or twice look at me very strangely; and he has certainly been a long time out of the room.”
