has heard every word that has been spoken on the journey.”
“How on earth is that managed?”
“Every one of the cabs is fitted with a telephonic arrangement communicating with the roof. The driver has only to button the wire of the transmitter up inside his coat so that the transmitter itself lies near to his ear, and he can hear even a whisper inside the cab.
“The man who is driving us, for instance, has a sort of retainer from the Russian Embassy to be on hand at certain hours on certain nights in the week. Our cabs are all better horsed, better appointed, and better driven than any others in London, and, consequently, they are favourites, especially among the young attachés, and are nearly always employed by them on their secret missions or love affairs, which, by the way, are very often the same thing. Our own Jehu has a job on to-night, from which we expect some results that will mystify the enemy not a little. We got our first suspicions of Ainsworth from a few incautious words that he spoke in one of our cabs.”
“It’s a splendid system, I should think, for discovering the movements of your enemies,” said Arnold, not without an uncomfortable reflection on the fact that he was himself now completely in the power of this terrible organisation, which had keen eyes and ready hands in every capital of the civilised world. “But how do you guard against treachery? It is well known that all the Governments of Europe are spending money like water to unearth this mystery of the Terror. Surely all your men cannot be incorruptible.”
“Practically they are so. The very mystery which enshrouds all our actions makes them so. We have had a few traitors, of course; but as none of them has ever survived his treachery by twenty-four hours, a bribe has lost its attraction for the rest.”
In such conversation as this the time was passed, while the cab crossed the river and made its way rapidly and easily along Kennington Road and Clapham Road to Clapham Common. At length it turned into the drive of one of those solid abodes of pretentious respectability which front the Common, and pulled up before a big stucco portico.
“Here we are!” exclaimed Colston, as the doors of the cab automatically opened. He got out first, and Arnold handed the case to him, and then followed him.
Without a word the driver turned his horse into the road again and drove off towards town, and as they ascended the steps the front door opened, and they went in, Colston saying as they did so —
“Is Mr. Smith at home?”
“Yes, sir; you are expected, I believe. Will you step into the drawing-room?” replied the clean-shaven and immaculately respectable man-servant, in evening dress, who had opened the door for them.
They were shown into a handsomely furnished room lit with electric light. As soon as the footman had closed the door behind him, Colston said —
“Well, now, here you are in the conspirators’ den, in the very headquarters of those Terrorists for whom Europe is being ransacked constantly without the slightest success. I have often wondered what the rigid respectability of Clapham Common would think if it knew the true character of this harmless-looking house. I hardly think an earthquake in Clapham Road would produce much more sensation than such a discovery would.
“And now,” he continued, his tone becoming suddenly much more serious, “in a few minutes you will be in the presence of the Inner Circle of the Terrorists, that is to say, of those who practically hold the fate of Europe in their hands. You know pretty clearly what they want with you. If you have thought better of the business that we have discussed you are still at perfect liberty to retire from it, on giving your word of honour not to disclose anything that I have said to you.”
“I have not the slightest intention of doing anything of the sort,” replied Arnold. “You know the conditions on which I came here. I shall put them before your Council, and if they are accepted your Brotherhood will, within their limits, have no more faithful adherent than I. If not, the business will simply come to an end as far as I am concerned, and your secret will be as safe with me as though I had taken the oath of membership.”
“Well said!” replied Colston, “and just what I expected you to say. Now listen to me for a minute. Whatever you may see or hear for the next few minutes say nothing till you are asked to speak. I will say all that is necessary at first. Ask no questions, but trust to anything that may seem strange being explained in due course — as it will be. A single indiscretion on your part might raise suspicions which would be as dangerous as they would be unfounded. When you are asked to speak do so without the slightest fear, and speak your mind as openly as you have done to me.”
“You need have no fear for me,” replied Arnold. “I think I am sensible enough to be prudent, and I am quite sure that I am desperate enough to be fearless. Little worse can happen to me than the fate that I was contemplating last night.”
As he ceased speaking there was a knock at the door. It opened and the footman reappeared, saying in the most commonplace fashion —
“Mr. Smith will be happy to see you now, gentlemen. “Will you kindly walk this way?”
They followed him out into the hall, and then, somewhat to Arnold’s surprise, down the stairs at the back, which apparently led to the basement of the house.
The footman preceded them to the basement floor and halted before a door in a little passage that looked like the entrance to a coal cellar. On this he knocked in peculiar fashion with the knuckles of one hand, while with the other he pressed the button of an electric bell concealed under the paper on the wall. The bell sounded faintly as though some distance off, and as it rang the footman said abruptly to Colston —
“Das Wort ist Freiheit.”
Arnold knew German enough to know that this meant “The word is ‘Freedom,’” but why it should have been spoken in a foreign language mystified him not a little.
While he was thinking about this the door opened, as if by a released spring, and he saw before him a long, narrow passage, lit by four electric arcs, and closed at the other end by a door, guarded by a sentry armed with a magazine rifle.
He followed Colston down the passage, and when within a dozen feet of the sentry, he brought his rifle to the “ready,” and the following strange dialogue ensued between him and Colston —
“Quien va?”
“Zwei Freunde der Bruderschaft.”
“Por la libertad?”
“Für Freiheit über alles!”
“Pass, friends.”
The rifle grounded as the words were spoken, and the sentry stepped back to the wall of the passage.
At the same moment another bell rang beyond the door, and then the door itself opened as the other had done.
They passed through, and it closed instantly behind them, leaving them in total darkness.
Colston caught Arnold by the arm, and drew him towards him, saying as he did so —
“What do you think of our system of passwords?”
“Pretty hard to get through unless one knew them, I should think. Why the different languages?”
“To make assurance doubly sure every member of the Inner Circle must be conversant with four European
