The Secret Adversary by Agatha Christie

In the meantime, the minutes were creeping by: 3.15, 3.20, 3.25, 3.27. Supposing Julius did not get there in time. 3.29…. Doors were banging. Tommy felt cold waves of despair pass over him. Then a hand fell on his shoulder.

“Here I am, son. Your British traffic beats description! Put me wise to the crooks right away.”

“That’s Whittington–there, getting in now, that big dark man. The other is the foreign chap he’s talking to.”

“I’m on to them. Which of the two is my bird?”

Tommy had thought out this question.

“Got any money with you?”

Julius shook his head, and Tommy’s face fell.

“I guess I haven’t more than three or four hundred dollars with me at the moment,” explained the American.

Tommy gave a faint whoop of relief.

“Oh, Lord, you millionaires! You don’t talk the same language! Climb aboard the lugger. Here’s your ticket. Whittington’s your man.”

“Me for Whittington!” said Julius darkly. The train was just starting as he swung himself aboard. “So long, Tommy.” The train slid out of the station.

Tommy drew a deep breath. The man Boris was coming along the platform towards him. Tommy allowed him to pass and then took up the chase once more.

From Waterloo Boris took the tube as far as Piccadilly Circus. Then he walked up Shaftesbury Avenue, finally turning off into the maze of mean streets round Soho. Tommy followed him at a judicious distance.

They reached at length a small dilapidated square. The houses there had a sinister air in the midst of their dirt and decay. Boris looked round, and Tommy drew back into the shelter of a friendly porch. The place was almost deserted. It was a cul-de-sac, and consequently no traffic passed that way. The stealthy way the other had looked round stimulated Tommy’s imagination. From the shelter of the doorway he watched him go up the steps of a particularly evil-looking house and rap sharply, with a peculiar rhythm, on the door. It was opened promptly, he said a word or two to the doorkeeper, then passed inside. The door was shut to again.

It was at this juncture that Tommy lost his head. What he ought to have done, what any sane man would have done, was to remain patiently where he was and wait for his man to come out again. What he did do was entirely foreign to the sober common sense which was, as a rule, his leading characteristic. Something, as he expressed it, seemed to snap in his brain. Without a moment’s pause for reflection he, too, went up the steps, and reproduced as far as he was able the peculiar knock.

The door swung open with the same promptness as before. A villainous-faced man with close-cropped hair stood in the doorway.

“Well?” he grunted.

It was at that moment that the full realization of his folly began to come home to Tommy. But he dared not hesitate. He seized at the first words that came into his mind.

“Mr. Brown?” he said.

To his surprise the man stood aside.

“Upstairs,” he said, jerking his thumb over his shoulder, “second door on your left.”

CHAPTER VIII THE ADVENTURES OF TOMMY

TAKEN aback though he was by the man’s words, Tommy did not hesitate. If audacity had successfully carried him so far, it was to be hoped it would carry him yet farther. He quietly passed into the house and mounted the ramshackle staircase. Everything in the house was filthy beyond words. The grimy paper, of a pattern now indistinguishable, hung in loose festoons from the wall. In every angle was a grey mass of cobweb.

Tommy proceeded leisurely. By the time he reached the bend of the staircase, he had heard the man below disappear into a back room. Clearly no suspicion attached to him as yet. To come to the house and ask for “Mr. Brown” appeared indeed to be a reasonable and natural proceeding.

At the top of the stairs Tommy halted to consider his next move. In front of him ran a narrow passage, with doors opening on either side of it. From the one nearest him on the left came a low murmur of voices. It was this room which he had been directed to enter. But what held his glance fascinated was a small recess immediately on his right, half concealed by a torn velvet curtain. It was directly opposite the left-handed door and, owing to its angle, it also commanded a good view of the upper part of the staircase. As a hiding-place for one or, at a pinch, two men, it was ideal, being about two feet deep and three feet wide. It attracted Tommy mightily. He thought things over in his usual slow and steady way, deciding that the mention of “Mr. Brown” was not a request for an individual, but in all probability a password used by the gang. His lucky use of it had gained him admission. So far he had aroused no suspicion. But he must decide quickly on his next step.
