to look for facts. Naturally, I do not expect my clients to supply them.'
Sir Charles slowly nodded his head, and seemed in some measure to recover confidence.
'Briefly, then,' he said, 'I believe my life is in danger.'
'You mean that there is someone who desires your death?'
'I do.'
'H'm,' said Harley, replacing the tin in the cupboard and striking a match. 'Even if the facts are scanty, no doubt you have fairly substantial grounds for such a suspicion?'
'I cannot say that they are substantial, Mr. Harley. They are rather more circumstantial. Frankly, I have forced myself to come here, and now that I have intruded upon your privacy, I realize my difficulties more keenly than ever.'
The expression of embarrassment upon the speaker's face had grown intense; and now he paused, bending forward in his chair. He seemed in his glance to appeal for patience on the part of his hearer, and Harley, lighting his pipe, nodded in understanding fashion. He was the last man in the world to jump to conclusions. He had learned by bitter experience that lightly to dismiss such cases as this of Sir Charles as coming within the province of delusion, was sometimes tantamount to refusing aid to a man in deadly peril.
'You are naturally anxious for the particulars,' Sir Charles presently resumed. 'They bear, I regret to say, a close resemblance to the symptoms of a well-known form of hallucination. In short, with one exception, they may practically all be classed under the head of surveillance.'
'Surveillance,' said Paul Harley. 'You mean that you are more or less constantly followed?'
'I do.'
'And what is your impression of this follower?'
'A very hazy one. To-night, as I came to your office, I have every reason to believe that someone followed me in a taxicab.'
'You came in a car?'
'I did.'
'And a cab followed you the whole way?'
'Practically the whole way, except that as my chauffeur turned into Chancery Lane, the cab stopped at the corner of Fleet Street.'
'Your idea is that your pursuer followed on foot from this point?'
'Such was my impression.'
'H'm, quite impossible. And is this sort of thing constant, Sir Charles?'
'It has been for some time past.'
'Anything else?'
'One very notable thing, Mr. Harley. I was actually assaulted less than a week ago within sight of my own house.'
'Indeed! Tell me of this.' Paul Harley became aware of an awakening curiosity. Sir Charles Abingdon was not the type of man who is lightly intimidated.
'I had been to visit a friend in the neighbourhood,' Sir Charles continued, 'whom I am at present attending professionally, although I am actually retired. I was returning across the square, close to midnight, when, fortunately for myself, I detected the sound of light, pattering footsteps immediately behind me. The place was quite deserted at that hour, and although I was so near home, the worst would have happened, I fear, if my sense of hearing had been less acute. I turned in the very instant that a man was about to spring upon me from behind. He was holding in his hand what looked like a large silk handkerchief. This encounter took place in the shadow of some trees, and beyond the fact that my assailant was a small man, I could form no impression of his identity.'
'What did you do?'
'I turned and struck out with my stick.'
'And then?'
'Then he made no attempt to contest the issue, but simply ran swiftly off, always keeping in the shadows of the trees.'
'Very strange,' murmured Harley. 'Do you think he had meant to drug you?'
'Maybe,' replied Sir Charles. 'The handkerchief was perhaps saturated with some drug, or he may even have designed to attempt to strangle me.'
'And you formed absolutely no impression of the man?'
'None whatever, Mr. Harley. When you see the spot at which the encounter took place, if you care to do so, you will recognize the difficulties. It is perfectly dark there after nightfall.'
'H'm,' mused Harley. 'A very alarming occurrence, Sir Charles. It must have shaken you very badly. But we must not overlook the possibility that this may have been an ordinary footpad.'
'His methods were scarcely those of a footpad,' murmured Sir Charles.
'I quite agree,' said Harley. 'They were rather Oriental, if I may say so.'
Sir Charles Abingdon started. 'Oriental!' he whispered. 'Yes, you are right.'
'Does this suggest a train of thought?' prompted Harley.
Sir Charles Abingdon cleared his throat nervously. 'It does, Mr. Harley,' he admitted, 'but a very confusing train of thought. It leads me to a point which I must mention, but which concerns a very well-known man. Before I proceed I should like to make it clear that I do not believe for a moment that he is responsible for this unpleasant business.'
Harley stared at him curiously. 'Nevertheless,' he said, 'there must be some data in your possession which suggest to your mind that he has some connection with it.'
'There are, Mr. Harley, and I should be deeply indebted if you could visit my house this evening, when I could place this evidence, if evidence it may be called, before you. I find myself in so delicate a position. If you are free I should welcome your company at dinner.'
Paul Harley seemed to be reflecting.
'Of course, Sir Charles,' he said, presently, 'your statement is very interesting and curious, and I shall naturally make a point of going fully into the matter. But before proceeding further there are two questions I should like to ask you. The first is this: What is the name of the 'well-known' man to whom you refer? And the second: If not he then whom do you suspect of being behind all this?'
'The one matter is so hopelessly involved in the other,' he finally replied, 'that although I came here prepared as I thought with a full statement of the case, I should welcome a further opportunity of rearranging the facts before imparting them to you. One thing, however, I have omitted to mention. It is, perhaps, of paramount importance. There was a robbery at my house less than a week ago.'
'What! A robbery! Tell me: what was stolen?'
'Nothing of the slightest value, Mr. Harley, to any one but myself—or so I should have supposed.' The speaker coughed nervously. 'The thief had gained admittance to my private study, where there are several cases of Oriental jewellery and a number of pieces of valuable gold and silverware, all antique. At what hour he came, how he gained admittance, and how he retired, I cannot imagine. All the doors were locked as usual in the morning and nothing was disturbed.'
'I don't understand, then.'
'I chanced to have occasion to open my bureau which I invariably keep locked. Immediately—immediately—I perceived that my papers were disarranged. Close examination revealed the fact that a short manuscript in my own hand, which had been placed in one of the pigeonholes, was missing.'
'A manuscript,' murmured Harley. 'Upon a technical subject?'
'Scarcely a technical subject, Mr. Harley. It was a brief account which I had vaguely contemplated publishing in one of the reviews, a brief account of a very extraordinary patient whom I once attended.'
'And had you written it recently?'
'No; some years ago. But I had recently added to it. I may say that it was my purpose still further to add to it, and with this object I had actually unlocked the bureau.'
'New facts respecting this patient had come into your possession?'
'They had.'
'Before the date of the attack upon you?'
