Suppose he were boldly to enter the room on the left of the passage. Would the mere fact of his having been admitted to the house be sufficient? Perhaps a further password would be required, or, at any rate, some proof of identity. The doorkeeper clearly did not know all the members of the gang by sight, but it might be different upstairs. On the whole it seemed to him that luck had served him very well so far, but that there was such a thing as trusting it too far. To enter that room was a colossal risk. He could not hope to sustain his part indefinitely; sooner or later he was almost bound to betray himself, and then he would have thrown away a vital chance in mere foolhardiness.
A repetition of the signal knock sounded on the door below, and Tommy, his mind made up, slipped quickly into the recess, and cautiously drew the curtain farther across so that it shielded him completely from sight. There were several rents and slits in the ancient material which afforded him a good view. He would watch events, and any time he chose could, after all, join the assembly, modelling his behaviour on that of the new arrival.
The man who came up the staircase with a furtive, soft-footed tread was quite unknown to Tommy. He was obviously of the very dregs of society. The low beetling brows, and the criminal jaw, the bestiality of the whole countenance were new to the young man, though he was a type that Scotland Yard would have recognized at a glance.
The man passed the recess, breathing heavily as he went. He stopped at the door opposite, and gave a repetition of the signal knock. A voice inside called out something, and the man opened the door and passed in, affording Tommy a momentary glimpse of the room inside. He thought there must be about four or five people seated round a long table that took up most of the space, but his attention was caught and held by a tall man with close-cropped hair and a short, pointed, naval-looking beard, who sat at the head of the table with papers in front of him. As the new-comer entered he glanced up, and with a correct, but curiously precise enunciation, which attracted Tommy’s notice, he asked:
“Your number, comrade?”
“Fourteen, gov’nor,” replied the other hoarsely.
“Correct.”
The door shut again.
“If that isn’t a Hun, I’m a Dutchman!” said Tommy to himself. “And running the show darned systematically too–as they always do. Lucky I didn’t roll in. I’d have given the wrong number, and there would have been the deuce to pay. No, this is the place for me. Hullo, here’s another knock.”
This visitor proved to be of an entirely different type to the last. Tommy recognized in him an Irish Sinn Feiner. Certainly Mr. Brown’s organization was a far-reaching concern. The common criminal, the well-bred Irish gentleman, the pale Russian, and the efficient German master of the ceremonies! Truly a strange and sinister gathering! Who was this man who held in his finger these curiously variegated links of an unknown chain?
In this case, the procedure was exactly the same. The signal knock, the demand for a number, and the reply “Correct.”
Two knocks followed in quick succession on the door below. The first man was quite unknown to Tommy, who put him down as a city clerk. A quiet, intelligent-looking man, rather shabbily dressed. The second was of the working classes, and his face was vaguely familiar to the young man.
Three minutes later came another, a man of commanding appearance, exquisitely dressed, and evidently well born. His face, again, was not unknown to the watcher, though he could not for the moment put a name to it.
After his arrival there was a long wait. In fact Tommy concluded that the gathering was now complete, and was just cautiously creeping out from his hiding-place, when another knock sent him scuttling back to cover.
This last-comer came up the stairs so quietly that he was almost abreast of Tommy before the young man had realized his presence.
He was a small man, very pale, with a gentle almost womanish air. The angle of the cheek-bones hinted at his Slavonic ancestry, otherwise there was nothing to indicate his nationality. As he passed the recess, he turned his head slowly. The strange light eyes seemed to burn through the curtain; Tommy could hardly believe that the man did not know he was there and in spite of himself he shivered. He was no more fanciful than the majority of young Englishmen, but he could not rid himself of the impression that some unusually potent force emanated from the man. The creature reminded him of a venomous snake.
