an enormous sprocket-wheel, indicating a gear of, at least, ninety.

      "Some scorcher or amateur racer, probably," I said, "who takes the opportunity of getting a spin on the wood pavement when the streets are empty." I looked round to see if I could identify the owner, but the machine appeared to be, for the moment, taking care of itself.

      King's Cross is one of those districts of which the inhabitants are slow in settling down for the night, and even at a quarter past one in the morning its streets are not entirely deserted. Here and there the glimmer of a street lamp or the far-reaching ray from a tall electric light reveals the form of some nocturnal prowler creeping along with cat-like stealthiness, or bursting, cat-like, into unmelodious song. Not greatly desirous of the society of these roysterers, we crossed quickly from the station into the Gray's Inn Road, now silent and excessively dismal in aspect, and took our way along the western side. We had turned the curve and were crossing Manchester Street, when a series of yelps from ahead announced the presence of a party of merry-makers, whom we were not yet able to see, however, for the night was an exceptionally dark one; but the sounds of revelry continued to increase in volume as we proceeded, until, as we passed Sidmouth Street, we came in sight of the revellers. They were some half-dozen in number, all of them roughs of the hooligan type, and they were evidently in boisterous spirits, for, as they passed the entrance to the Royal Free Hospital, they halted and battered furiously at the gate. Shortly after this exploit they crossed the road on to our side, whereupon Thorndyke caught my arm and slackened his pace.

      "Let them draw ahead," said he. "It is a wise precaution to give all hooligan gangs a very wide berth at this time of night. We had better turn down Heathcote Street and cross Mecklenburgh Square."

      We continued to walk on at reduced speed until we reached Heathcote Street, into which we turned and so entered Mecklenburgh Square, where we mended our pace once more.

      "The hooligan," pursued Thorndyke, as we walked briskly across the silent square, "covers a multitude of sins, ranging from highway robbery with violence and paid assassination (technically known as 'bashing') down to the criminal folly of the philanthropic magistrate, who seems to think that his function in the economy of nature is to secure the survival of the unfittest. There goes a cyclist along Guildford Street. I wonder if that is our strenuous friend from the station. If so, he has slipped past the hooligans."

      We were just entering Doughty Street, and, as Thorndyke spoke, a man on a bicycle was visible for an instant at the crossing of the two streets. When we reached Guildford Street we both looked down the long, lamp-lighted vista, but the cyclist had vanished.

      "We had better go straight on into Theobald's Road," said Thorndyke, and we accordingly pursued our way up the fine old-world street, from whose tall houses our footfalls echoed, so that we seemed to be accompanied by an invisible multitude, until we reached that part where it unaccountably changes its name and becomes John Street.

      "There always seems to me something very pathetic about these old Bloomsbury streets," said Thorndyke, "with their faded grandeur and dignified seediness. They remind me of some prim and aged gentlewoman in reduced circumstances who—Hallo! What was that?"

      A faint, sharp thud from behind had been followed instantly by the shattering of a ground-floor window in front.

      We both stopped dead and remained, for a couple of seconds, staring into the gloom, from whence the first sound had come; then Thorndyke darted diagonally across the road at a swift run and I immediately followed.

      At the moment when the affair happened we had gone about forty yards up John Street, that is, from the place where it is crossed by Henry Street, and we now raced across the road to the further corner of the latter street. When we reached it, however, the little thoroughfare was empty, and, as we paused for a moment, no sound of retreating footsteps broke the silence.

      "The shot certainly came from here!" said Thorndyke; "come on," and he again broke into a run. A few yards up the street a mews turns off to the left, and into this my companion plunged, motioning me to go straight on, which I accordingly did, and in a few paces reached the top of the street. Here a narrow thoroughfare, with a broad, smooth pavement, bears off to the left, parallel with the mews, and, as I arrived at the corner and glanced up the little street, I saw a man on a bicycle gliding swiftly and silently towards Little James' Street.

      With a mighty shout of "Stop thief!" I started in hot pursuit, but, though the man's feet were moving in an apparently leisurely manner, he drew ahead at an astonishing pace, in spite of my efforts to overtake him; and it then dawned upon me that the slow revolutions of his feet were due, in reality, to the unusually high gear of the machine that he was riding. As I realised this, and at the same moment recalled the bicycle that we had seen in the station, the fugitive swung round into Little James' Street and vanished.

      The speed at which the man was travelling made further pursuit utterly futile, so I turned and walked back, panting and perspiring from the unwonted exertion. As I re-entered Henry Street, Thorndyke emerged from the mews and halted on seeing me.

      "Cyclist?" he asked laconically, as I came up.

      "Yes," I answered; "riding a machine geared up to about ninety."

      "Ah! he must have followed us from the station," said Thorndyke. "Did you notice if he was carrying anything?"

      "He had a walking-stick in his hand. I didn't see anything else."

      "What sort of walking-stick?"

      "I couldn't see very distinctly. It was a stoutish stick—I should say a Malacca, probably—and it had what looked like a horn handle. I could see that as he passed a street lamp."

      "What kind of lamp had he?"

      "I couldn't see; but, as he turned the corner, I noticed that it seemed to burn very dimly."

      "A little vaseline, or even oil, smeared on the outside of the glass will reduce the glare of a lamp very appreciably," my companion remarked, "especially on a dusty road. Ha! here is the proprietor of the broken window. He wants to know, you know."

      We had once more turned into John Street and now perceived a man, standing on the wide doorstep of the house with the shattered window, looking anxiously up and down the street.

      "Do either of you gents know anything about this here?" he asked, pointing to the broken pane.

      "Yes," said Thorndyke, "we happened to be passing when it was done; in fact," he added, "I rather suspect that the missile, whatever it was, was intended for our benefit."

      "Oh!" said the man. "Who done it?"

      "That I can't say," replied Thorndyke. "Whoever he was, he made off on a bicycle and we were unable to catch him."

      "Oh!" said the man once more, regarding us with growing suspicion. "On a bicycle, hay! Dam funny, ain't it? What did he do it with?"

      "That is what I should like to find out," said Thorndyke. "I see this house is empty."

      "Yes, it's empty—leastways it's to let. I'm the caretaker. But what's that got to do with it?"

      "Merely this," answered Thorndyke, "that the object—stone, bullet or whatever it may have been—was aimed, I believe, at me, and I should like to ascertain its nature. Would you do me the favour of permitting me to look for it?"

      The caretaker was evidently inclined to refuse this request, for he glanced suspiciously from my companion to me once or twice before replying, but, at length, he turned towards the open door and gruffly invited us to enter.

      A paraffin lamp was on the floor in a recess of the hall, and this our conductor took up when he had elosed the street door.

      "This is the room," he said, turning the key and thrusting the door open; "the library they call it, but it's the front parlour in plain English." He entered and, holding the lamp above his head, stared balefully at the broken window.

      Thorndyke glanced quickly along the floor in the direction that the missile would have taken, and then said—

      "Do
