in Essex. It is an out-of-the-way place, but if we catch the seven-fifteen train from Liverpool Street, we shall be there in an hour and a half.”
“And as to the return? You know the trains, I suppose?”
“Oh yes,” replied our client; “I will see that you don’t miss your train back.”
“Then I will be with you in a minute,” said Thorndyke; and, taking the still-bubbling flask, he retired to the laboratory, whence he returned in a few minutes carrying his hat and overcoat.
The cab which had brought our client was still waiting, and we were soon rattling through the streets towards the station, where we arrived in time to furnish ourselves with dinner-baskets and select our compartment at leisure.
During the early part of the journey our companion was in excellent spirits. He despatched the cold fowl from the basket and quaffed the rather indifferent claret with as much relish as if he had not had a single relation in the world, and after dinner he became genial to the verge of hilarity. But, as time went on, there crept into his manner a certain anxious restlessness. He became silent and preoccupied, and several times furtively consulted his watch.
“The train is confoundedly late!” he exclaimed irritably. “Seven minutes behind time already!”
“A few minutes more or less are not of much consequence,” said Thorndyke.
“No, of course not; but still—Ah, thank Heaven, here we are!”
He thrust his head out of the off-side window, and gazed eagerly down the line; then, leaping to his feet, he bustled out on to the platform while the train was still moving.
Even as we alighted a warning bell rang furiously on the up-platform, and as Mr. Barton hurried us through the empty booking-office to the outside of the station, the rumble of the approaching train could be heard above the noise made by our own train moving off.
“My carriage doesn’t seem to have arrived yet,” exclaimed Mr. Barton, looking anxiously up the station approach. “If you will wait here a moment, I will go and make inquiries.”
He darted back into the booking-office and through it on to the platform, just as the up-train roared into the station. Thorndyke followed him with quick but stealthy steps, and, peering out of the booking-office door, watched his proceedings; then he turned and beckoned to me.
“There he goes,” said he, pointing to an iron footbridge that spanned the line; and, as I looked, I saw, clearly defined against the dim night sky, a flying figure racing towards the “up” side.
It was hardly two-thirds across when the guard’s whistle sang out its shrill warning.
“Quick, Jervis,” exclaimed Thorndyke; “she’s off!”
He leaped down on to the line, whither I followed instantly, and, crossing the rails, we clambered up together on to the foot-board opposite an empty first-class compartment. Thorndyke’s magazine knife, containing, among other implements, a railway-key, was already in his hand. The door was speedily unlocked, and, as we entered, Thorndyke ran through and looked out on to the platform.
“Just in time!” he exclaimed. “He is in one of the forward compartments.”
He relocked the door, and, seating himself, proceeded to fill his pipe.
“And now,” said I, as the train moved out of the station, “perhaps you will explain this little comedy.”
“With pleasure,” he replied, “if it needs any explanation. But you can hardly have forgotten Mr. James’s flattering remarks in his report of the Greek Street incident, clearly giving the impression that the mysterious document was in my possession. When I read that, I knew I must look out for some attempt to recover it, though I hardly expected such promptness. Still, when Mr. Barton called without credentials or appointment, I viewed him with some suspicion. That suspicion deepened when he wanted us both to come. It deepened further when I found an impossible quantity of arsenic in his sample, and it gave place to certainty when, having allowed him to select the trains by which we were to travel, I went up to the laboratory and examined the time-table; for I then found that the last train for London left Rexford ten minutes after we were due to arrive. Obviously this was a plan to get us both safely out of the way while he and some of his friends ransacked our chambers for the missing document.”
“I see; and that accounts for his extraordinary anxiety at the lateness of the train. But why did you come, if you knew it was a ‘plant’?”
“My dear fellow,” said Thorndyke, “I never miss an interesting experience if I can help it. There are possibilities in this, too, don’t you see?”
“But supposing his friends have broken into our chambers already?”
“That contingency has been provided for; but I think they will wait for Mr. Barton—and us.”
Our train, being the last one up, stopped at every station, and crawled slothfully in the intervals, so that it was past eleven o’clock when we reached Liverpool Street. Here we got out cautiously, and, mingling with the crowd, followed the unconscious Barton up the platform, through the barrier, and out into the street. He seemed in no special hurry, for, after pausing to light a cigar, he set off at an easy pace up New Broad Street.
Thorndyke hailed a hansom, and, motioning me to enter, directed the cabman to drive to Clifford’s Inn Passage.
“Sit well back,” said he, as we rattled away up New Broad Street. “We shall be passing our gay deceiver presently—in fact, there he is, a living, walking illustration of the folly of underrating the intelligence of one’s adversary.”
At Clifford’s Inn Passage we dismissed the cab, and, retiring into the shadow of the dark, narrow alley, kept an eye on the gate of Inner Temple Lane. In about twenty minutes we observed our friend approaching on the south side of Fleet Street. He halted at the gate, plied the knocker, and after a brief parley with the night-porter vanished through the wicket. We waited yet five minutes more, and then, having given him time to get clear of the entrance, we crossed the road.
The porter looked at us with some surprise.
“There’s a gentleman just gone down to your chambers, sir,” said he. “He told me you were expecting him.”
“Quite right,” said Thorndyke, with a dry smile, “I was. Good-night.”
We slunk down the lane, past the church, and through the gloomy cloisters, giving a wide berth to all lamps and lighted entries, until, emerging into Paper Buildings, we crossed at the darkest part to King’s Bench Walk, where Thorndyke made straight for the chambers of our friend Anstey, which were two doors above our own.
“Why are we coming here?” I asked, as we ascended the stairs.
But the question needed no answer when we reached the landing, for through the open door of our friend’s chambers I could see in the darkened room Anstey himself with two uniformed constables and a couple of plain-clothes men.
“There has been no signal yet, sir,” said one of the latter, whom I recognized as a detective-sergeant of our division.
“No,” said Thorndyke, “but the M.C. has arrived. He came in five minutes before us.”
“Then,” exclaimed Anstey, “the ball will open shortly, ladies and gents. The boards are waxed, the fiddlers are tuning up, and—”
“Not quite so loud, if you please, sir,” said the sergeant. “I think there is somebody coming up Crown Office Row.”
The ball had, in fact, opened. As we peered cautiously out of the open window, keeping well back in the darkened room, a stealthy figure crept out of the shadow, crossed the road, and stole noiselessly into the entry of Thorndyke’s chambers. It was quickly followed by a second figure, and then by a third, in which I recognized our elusive client.
“Now listen for the signal,” said Thorndyke. “They won’t waste
