The two men stepped into a square, finely furnished hall with a fireplace on the same side as the door, and a staircase opposite. The dining-room door stood open on their right, and as Sir Julian rang the bell a man-servant appeared at the far end of the hall.
"What will you take?" asked the doctor.
"After that dreadfully cold place," said Parker, "what I really want is gallons of hot tea, if you, as a nerve specialist, can bear the thought of it.''
"Provided you allow of a judicious blend of China with it," replied Sir Julian in the same tone, "I have no objection to make. Tea in the library at once," he added to the servant, and led the way upstairs.
"I don't use the downstairs rooms much, except the dining-room," he explained, as he ushered his guest into a small but cheerful library on the first floor. "This room leads out of my bedroom and is more convenient. I only live part of my time here, but it's very handy for my research work at the hospital. That's what I do there, mostly. It's a fatal thing for a theorist, Mr. Parker, to let the practical work get behindhand. Dissection is the basis of all good theory and all correct diagnosis. One must keep one's hand and eye in training. This place is far more important to me than Harley Street, and some day I shall abandon my consulting practice altogether and settle down here to cut up my subjects and write my books in peace. So many things in this life are a waste of time, Mr. Parker."
Mr. Parker assented to this.
"Very often," said Sir Julian, "the only time I get for any research work–necessitating as it does the keenest observation and the faculties at their acutest–has to be at night, after a long day's work and by artificial light, which, magnificent as the lighting of the dissecting room here is, is always more trying to the eyes than daylight. Doubtless your own work has to be carried on under even more trying conditions."
"Yes, sometimes," said Parker; "but then you see," he added, "the conditions are, so to speak, part of the work."
"Quite so, quite so," said Sir Julian; "you mean that the burglar, for example, does not demonstrate his methods in the light of day, or plant the perfect footmark in the middle of a damp patch of sand for you to analyze."
"Not as a rule," said the detective, "but I have no doubt many of your diseases work quite as insidiously as any burglar."
"They do, they do," said Sir Julian, laughing, "and it is my pride, as it is yours, to track them down for the good of society. The neuroses, you know, are particularly clever criminals–they break out into as many disguises as–"
"As Leon Kestrel, the Master-Mummer," suggested Parker, who read railway-stall detective stories on the principle of the 'busman's holiday.
"No doubt," said Sir Julian, who did not, "and they cover up their tracks wonderfully. But when you can really investigate, Mr. Parker, and break up the dead, or for preference the living body with the scalpel, you always find the footmarks–the little trail of ruin or disorder left by madness or disease or drink or any other similar pest. But the difficulty is to trace them back, merely by observing the surface symptoms–the hysteria, crime, religion, fear, shyness, conscience, or whatever it may be; just as you observe a theft or a murder and look for the footsteps of the criminal, so I observe a fit of hysterics or an outburst of piety and hunt for the little mechanical irritation which has produced it."
"You regard all these things as physical?"
"Undoubtedly. I am not ignorant of the rise of another school of thought, Mr. Parker, but its exponents are mostly charlatans or self-deceivers. '

' that, like Sludge the Medium, they are beginning to believe their own nonsense. I should like to have the exploring of some of their brains, Mr. Parker; I would show you the little faults and landslips in the cells–the misfiring and short-circuiting of the nerves, which produce these notions and these books. At least," he added, gazing sombrely at his guest, "at least, if I could not quite show you to-day, I shall be able to do so to-morrow–or in a year's time–or before I die."
He sat for some minutes gazing into the fire, while the red light played upon his tawny beard and struck out answering gleams from his compelling eyes.
Parker drank tea in silence, watching him. On the whole, however, he remained but little interested in the causes of nervous phenomena, and his mind strayed to Lord Peter, coping with the redoubtable Crimplesham down in Salisbury. Lord Peter had wanted him to come: that meant, either that Crimplesham was proving recalcitrant or that a clue wanted following. But Bunter had said that to-morrow would do, and it was just as well. After all the Battersea affair was not Parker's case; he had already wasted valuable time attending an inconclusive inquest, and he really ought to get on with his legitimate work. There was still Levy's secretary to see and the little matter of the Peruvian Oil to be looked into. He looked at his watch.
"I am very much afraid–if you will excuse me–" he murmured.
Sir Julian came back with a start to the consideration of actuality.
"Your work calls you?" he said smiling. "Well, I can understand that. I won't keep you. But I wanted to say something to you in connection with your present inquiry–only I hardly know–I hardly like–"
Parker sat down again, and banished every indication of hurry from his face and attitude.
"I shall be very grateful for any help you can give me," he said.
"I'm afraid it's more in the nature of hindrance," said Sir Julian, with a short laugh. "It's a case of destroying a clue for you, and a breach of professional confidence on my side. But since–accidentally–a certain amount has come out, perhaps the whole had better do so."
Mr. Parker made the encouraging noise which, among laymen, supplies the place of the priest's insinuating, "Yes, my son?"
"Sir Reuben Levy's visit on Monday night was to me," said Sir Julian.
"Yes?" said Mr. Parker, without expression.
"He found cause for certain grave suspicions concerning his health," said Sir Julian, slowly, as though weighing how much he could in honour disclose to a stranger. "He came to me, in preference to his own medical man, as he was particularly anxious that the matter should be kept from his wife. As I told you, he knew me fairly well, and Lady Levy had consulted me about a nervous disorder in the summer."
"Did he make an appointment with you?" asked Parker.
"I beg your pardon," said the other, absently.
"Did he make an appointment?"
"An appointment? Oh, no! He turned up suddenly in the evening after dinner when I wasn't expecting him. I took him up here and examined him, and he left me somewhere about ten o'clock, I should think."
"May I ask what was the result of your examination?"
"Why do you want to know?"
"It might illuminate–well, conjecture as to his subsequent conduct," said Parker, cautiously. This story seemed to have little coherence with the rest of the business, and he wondered whether coincidence was alone responsible for Sir Reuben's disappearance on the same night that he visited the doctor.
"I see," said Sir Julian. "Yes. Well, I will tell you in confidence that I saw grave grounds of suspicion, but as yet, no absolute certainty of mischief."
"Thank you. Sir Reuben left you at ten o'clock?"
"Then or thereabouts. I did not at first mention the matter as it was so very much Sir Reuben's wish to keep his visit to me secret, and there was no question of accident in the street or anything of that kind, since he reached home safely at midnight."
"Quite so," said Parker.
"It would have been, and is, a breach of confidence," said Sir Julian, "and I only tell you now because Sir Reuben was accidentally seen, and because I would rather tell you in private than have you ferreting round here and questioning my servants, Mr. Parker. You will excuse my frankness."
"Certainly," said Parker. "I hold no brief for the pleasantness of my profession, Sir Julian. I am very much obliged to you for telling me this. I might otherwise have wasted valuable time following up a false trail."
"I am sure I need not ask you, in your turn, to respect this confidence," said the doctor. "To publish the matter abroad could only harm Sir Reuben and pain his wife, besides placing me in no favourable light with my patients."
"I promise to keep the thing to myself," said Parker, "except of course," he added hastily, "that I must inform my colleague."
"You have a colleague in the case?"
"I have."
"What sort of person is he?"
"He will be perfectly discreet, Sir Julian."
"Is he a police officer?"
"You need not be afraid of your confidence getting into the records at Scotland Yard."
"I see that you know how to be discreet, Mr. Parker."
"We also have our professional etiquette, Sir Julian."
On returning to Great Ormond Street, Mr. Parker found a wire awaiting him, which said: "Do not trouble to come. All well. Returning to-morrow. Wimsey."
VII
On returning to the flat just before lunch-time on the following morning, after a few confirmatory researches in Balham and the neighbourhood of Victoria Station, Lord Peter was greeted at the door by Mr. Bunter (who had gone straight home from Waterloo) with a telephone message and a severe and nursemaid-like eye.
