What he told me was certainly remarkable. The whole of the facts were, indeed, astounding.
While the unfortunate Professor lay dead in his laboratory in London he was, at the same time, here, in Edinburgh, making an attempt at disguise, and sending a reassuring telegram to his daughter!
That Professor Greer had been killed there was not the slightest doubt – killed, too, behind locked doors, in circumstances which themselves formed a complete and inscrutable mystery. Then, if so, who was this man who had left London with the Professor’s luggage, had arrived in Edinburgh, and whom the hotel-servants and others had identified by his portrait?
If he were not the Professor, then who could he have been? One thing was certain, he could not have been the actual assassin. Yet if not, why had he taken such pains to disguise his appearance?
The theory of Greer having a double I put aside at once. Doubles only exist in the realms of fiction. Here, however, I was dealing with hard, solid facts.
Each phase of the intricate problem became more and more complicated as I endeavoured to analyse it. That grey, wintry afternoon I wandered about the damp streets of Edinburgh, gazing aimlessly in the shop windows, and afterwards sat for a full hour upon a seat in the deserted public gardens below the Castle, thinking and wondering until the gloomy twilight began to creep on, and the lights along Princes Street commenced to glimmer.
Then, rising, I set off again across the North Bridge, and through High Street and Johnstone Terrace to the Caledonian Station, and by George Street and St. Andrew’s Street back to the Waverley, a tour of the centre of the city. I was merely killing time, for I had decided to take the night express back to King’s Cross.
When I re-entered the hotel it was nearly seven o’clock, and, as I did so, the porter at the revolving door in Princes Street touched his cap and informed me that the hairdresser desired to see me again.
I ascended to the first floor, and entered the saloon, where I found the German with whom before luncheon I had spoken. He was seated alone, reading a newspaper.
“Ach, sir!” he exclaimed; “I thought perhaps you had left! I’m very glad you are still here! A most curious circumstance occurred this afternoon when I went off duty as usual from three till five. I live in Forth Street, at the back of the Theatre Royal, and while walking towards home along Broughton Street, I came face to face with the gentleman for whom you are searching.”
“You’ve seen him!” I gasped, half-inclined to disbelieve the man’s story, for he was evidently on the look-out for a substantial tip.
“Yes, he recognised me, and tried to avert his face. But I managed to get a good look at him, and am absolutely certain that I’m not mistaken. He was dressed differently, and looks many years younger than when I first saw him wearing his beard.”
“Then he is still in hiding here!” I gasped quickly. “Did you follow him?”
“I did. I had to exercise considerable caution, for he evidently fears that he is being traced. His attitude was essentially that of a man dreading recognition. He may be suspicious that you are here, sir.”
“But have you discovered where he is living?” I demanded breathlessly, my heart leaping.
“Yes, sir,” replied the German; “I have.”

I Learn Something Interesting
Ten minutes later I was with the German hairdresser on a tram-car, going up Regent Road, towards Abbey Hill. On turning into the London Road at the station, we descended, and, crossing the main thoroughfare, entered one of the narrow, ill-lit turnings on the left, the name of which I was unable to see.
“I don’t know whom to ask for,” I remarked to my companion, as we hurried along together.
“I can only point you out the house where your friend is in hiding,” replied the man. “You, of course, know more of his habits than I do.”
In a few moments we passed before a tall, drab, dingy-looking house, which the German pointed out was the false Professor’s secret abode.
I longed for the presence of Kershaw Kirk, for I knew not how to act. I reflected, however, that the reason of my journey to Edinburgh was to clear up the mystery, and this thought prompted me to action.
So while he waited in the semi-darkness at the next corner, I returned to the house and rang the bell. To the door came a rather dishevelled girl of about eighteen, evidently the daughter of the occupier.
“You have a gentleman living here,” I said. “Would you kindly tell him that Mr Kirk desires to see him?”
“The gentleman’s no longer here, sir,” replied the girl, in broad Scotch.
“Gone!” I ejaculated.
“Yes, sir. Mr Martin’s who you mean, I suppose, for he’s the only gentleman mother has had. He packed his things, and left for the station an hour ago.”
My heart fell. He had evidently realised that the German was following him, and had escaped us!
“Can I see your mother?” I asked. Whereupon I was invited into the small narrow hall of the musty-smelling house, and a thin-faced, angular woman in rusty black came forward.
“Pray pardon my troubling you,” I said apologetically, “but I have an urgent message to give to Mr Martin, who, I understand, has been staying with you.” It was an advantage that the girl had unwittingly betrayed the name which the false Professor had adopted.
“Mr Martin’s gone, sir. He left this evening.”
“So your daughter tells me. But haven’t you any idea where he intended going?”
The woman hesitated, and by that slight pause I felt convinced she knew something which she intended keeping to herself.
“No, sir, he left quite suddenly,” was her hurried reply. “He had been out all day, and, returning about five, packed up his things, paid me what he owed me, together with a week’s rent in lieu of notice, and, getting a cab, drove away.”
“To the station – eh?”
“Yes, I heard him tell the man to drive to Princes Street.”
“He hadn’t been very long with you, had he?”
“About a week. He came on the Monday, telling me that he had been recommended by a friend of his, an actor. I let rooms to professionals,” she added, in explanation.
“He is a very reticent man,” I remarked. “I suppose he seldom went out?”
“No; he used to read all day, and go for just half-an-hour’s stroll at night. He struck me as a rather eccentric man.”
“So he is,” I laughed. “I’m an old friend of his, so, of course, I know. I hope he is not in your debt. If so, please tell me and I’ll liquidate it.”
“Oh, not at all, sir. He’s paid for everything,” declared the woman, upon whom my ready offer to pay her lodger’s debts had evidently made an impression. “His sudden departure mystified us.”
“Did he receive many letters?”
“Only two – and a telegram you sent him – which I found dropped by the side of his dressing-table.”
“From me?” I echoed, yet next instant recollecting that I had given my name as Kirk.
“Yes, you telegraphed to him several days ago to meet you at the Caledonian Hotel in Glasgow. You are Mr Kirk, are you not?”
“Ah, of course, I recollect,” I laughed. “Do you think he’s gone to Glasgow?” I asked, as the sudden thought occurred to me.
“Well, sir,” replied the woman, “as you are such an intimate friend of Mr Martin’s, I think I ought to tell you that, before leaving to-night, he asked me in confidence to repeat any telegram that might come for him to the Caledonian in Glasgow, but asking me at the same time to give no information to anyone who might call and make inquiries as to his whereabouts.”
“Then he’s gone to Glasgow to-night!” I exclaimed, with sudden enthusiasm. “If I follow at once, I may find him!”
