That his ready acceptance had immensely relieved the troubled mind of Sir Charles was evident enough. His visitor stood up. "I am not prone to sickly fancies, Mr. Harley," he said. "But a conviction has been growing upon me for some time that I have incurred, how I cannot imagine, but that nevertheless I have incurred powerful enmity. I trust our evening's counsel may enable you, with your highly specialized faculties, to detect an explanation."
And it was instructive to note how fluently he spoke now that he found himself temporarily relieved of the necessity of confessing the source of his mysterious fears.
Chapter 2 THE SIXTH SENSE
Paul Harley stepped into his car in Chancery Lane. "Drive in the direction of Hyde Park Corner," he directed the chauffeur. "Go along the Strand."
Glancing neither right nor left, he entered the car, and presently they were proceeding slowly with the stream of traffic in the Strand. "Pull up at the Savoy," he said suddenly through the tube.
The car slowed down in that little bay which contains the entrance to the hotel, and Harley stared fixedly out of the rear window, observing the occupants of all other cars and cabs which were following. For three minutes or more he remained there watching. "Go on," he directed.
Again they proceeded westward and, half-way along Piccadilly, "Stop at the Ritz," came the order.
The car pulled up before the colonnade and Harley, stepping out, dismissed the man and entered the hotel, walked through to the side entrance, and directed a porter to get him a taxicab. In this he proceeded to the house of Sir Charles Abingdon. He had been seeking to learn whether he was followed, but in none of the faces he had scrutinized had he detected any interest in himself, so that his idea that whoever was watching Sir Charles in all probability would have transferred attention to himself remained no more than an idea. For all he had gained by his tactics, Sir Charles's theory might be no more than a delusion after all.
The house of Sir Charles Abingdon was one of those small, discreet establishments, the very neatness of whose appointments inspires respect for the occupant. If anything had occurred during the journey to suggest to Harley that Sir Charles was indeed under observation by a hidden enemy, the suave British security and prosperity of his residence must have destroyed the impression.
As the cab was driven away around the corner, Harley paused for a moment, glancing about him to right and left and up at the neatly curtained windows. In the interval which had elapsed since Sir Charles's departure from his office, he had had leisure to survey the outstanding features of the story, and, discounting in his absence the pathetic sincerity of the narrator, he had formed the opinion that there was nothing in the account which was not susceptible of an ordinary prosaic explanation.
Sir Charles's hesitancy in regard to two of the questions asked had contained a hint that they might involve intimate personal matters, and Harley was prepared to learn that the source of the distinguished surgeon's dread lay in some unrevealed episode of the past. Beyond the fact that Sir Charles was a widower, he knew little or nothing of his private life; and he was far too experienced an investigator to formulate theories until all the facts were in his possession. Therefore it was with keen interest that he looked forward to the interview.
Familiarity with crime, in its many complexions, East and West, had developed in Paul Harley a sort of sixth sense. It was an evasive, fickle thing, but was nevertheless the attribute which had made him an investigator of genius. Often enough it failed him entirely. It had failed him to-night—or else no one had followed him from Chancery Lane.
It had failed him earlier in the evening when, secretly, he had watched from the office window Sir Charles's car proceeding toward the Strand. That odd, sudden chill, as of an abrupt lowering of the temperature, which often advised him of the nearness of malignant activity, had not been experienced.
Now, standing before Sir Charles's house, he "sensed" the atmosphere keenly—seeking for the note of danger.
There had been a thunder shower just before he had set out, and now, although rain had ceased, the sky remained blackly overcast and a curious, dull stillness was come. The air had a welcome freshness and the glistening pavements looked delightfully cool after the parching heat of the day. In the quiet square, no doubt, it was always restful in contrast with the more busy highroads, and in the murmur of distant traffic he found something very soothing. About him then were peace, prosperity, and security.
Yet, as he stood there, waiting—it came to him: the note of danger. Swiftly he looked to right and left, trying to penetrate the premature dusk. The whole complexion of the matter changed. Some menace intangible now, but which at any moment might become evident—lay near him. It was sheer intuition, no doubt, but it convinced him.
A moment later he had rung the bell; and as a man opened the door, showing a easy and well-lighted lobby within, the fear aura no longer touched Paul Harley. Out from the doorway came hominess and that air of security and peace which had seemed to characterize the house when viewed from outside. The focus of menace, therefore, lay not inside the house of Sir Charles but without. It was very curious. In the next instant came a possible explanation.
"Mr. Paul Harley?" said the butler tentatively.
"Yes, I am he."
"Sir Charles is expecting you, sir. He apologizes for not being in to receive you, but he will only be absent a few minutes."
"Sir Charles has been called out?" inquired Harley as he handed hat and coat to the man.
"Yes, sir. He is attending Mr. Chester Wilson on the other side of the square, and Mr. Wilson's man rang up a few moments ago requesting Sir Charles to step across."
"I see," murmured Harley, as the butler showed him into a small but well-filled library on the left of the lobby.
Refreshments were set invitingly upon a table beside a deep lounge chair. But Harley declined the man's request to refresh himself while waiting and began aimlessly to wander about the room, apparently studying the titles of the works crowding the bookshelves. As a matter of fact, he was endeavouring to arrange certain ideas in order, and if he had been questioned on the subject it is improbable that he could have mentioned the title of one book in the library.
His mental equipment was of a character too rarely met with in the profession to which he belonged. While up to the very moment of reaching Sir Charles's house he had doubted the reality of the menace which hung over this man, the note of danger which he had sensed at the very threshold had convinced him, where more ordinary circumstantial evidence might have left him in doubt.
It was perhaps pure imagination, but experience had taught him that it was closely allied to clairvoyance.
Now upon his musing there suddenly intruded sounds of a muffled altercation. That is to say, the speakers, who were evidently in the lobby beyond the library door, spoke in low tones, perhaps in deference to the presence of a visitor. Harley was only mildly interested, but the voices had broken his train of thought, and when presently the door opened to admit a very neat but rather grim-looking old lady he started, then looked across at her with a smile.
Some of the grimness faded from the wrinkled old face, and the housekeeper, for this her appearance proclaimed her to be, bowed in a queer Victorian fashion which suggested that a curtsy might follow. One did not follow, however. "I am sure I apologize, sir," she said. "Benson did not tell me you had arrived."
"That's quite all right," said Harley, genially.
His smile held a hint of amusement, for in the comprehensive glance which the old lady cast across the library, a glance keen to detect disorder and from which no speck of dust could hope to conceal itself, there remained a trace of that grimness which he had detected at the moment of her entrance. In short, she was still bristling from a recent encounter. So much so that detecting something sympathetic in Harley's smile she availed herself of the presence of a badly arranged vase of flowers to linger and to air her grievances.
