"One drink," he said, "and we must be off."

The night was thick. A mist which had been gathering since sunset now turned to a soft drizzle of rain. Crabb, hands in pockets and shoulders bent, walked with a rapid and shambling gait up the street.

"We can't risk the cars or a cab in this," muttered Crabb. "We might do it, but it's not worth the risk. Can you walk? It's not over three miles."

It was after one o'clock before they reached Highland Terrace. Without stopping they examined the German emba.s.sy at long range from the distant side of Ma.s.sachusetts Avenue. A gas lamp sputtered dimly under the _porte-cochere_. Another light gleamed far up in the slanting roof.

Crabb led the way around and into the alley in the rear. It was long, badly lighted and ran the entire length of the block.

"I got the details in the city plot-book from a real-estate man this afternoon. He thinks I'm going to buy next door. I wanted to be particular about the alleys and back entrances." Crabb chuckled.

Burnett looked along the backs of the row of N Street houses. They were all as stolid as sphinxes. Several lights at wide intervals burned dimly. The night was chill for the season, and all the windows were down. The occasion was propitious. The rear of the emba.s.sy was dark, except for a dim glow in a window on the second floor.

"That should be Arnim's room," said Crabb.

He tried the back gate. It was unlocked. Noiselessly they entered, closing it after them. There was a rain spout, which Crabb eyed hopefully; but they found better luck in the shape of a thirty-foot ladder along the fence.

"A positive invitation," whispered Crabb, joyfully. "Here, Ross; in the shadow. Once on the back building the deed is done. Quiet, now. You hold it and I'll go up."

Burnett did not falter. But his hands were cold, and he was trembling from top to toe with excitement. He could not but admire Crabb's composure as he went firmly up the rungs.

He saw him reach the roof and draw himself over the coping, and in a moment Burnett, less noiselessly but safely, had joined his fellow criminal by the window. There they waited a moment, listening. A cab clattered down Fifteenth Street, and the gongs on the car line clanged in reply, but that was all.

Crabb stealthily arose and peered into the lighted window. It was a study. The light came from a lamp with a green shade. Under its glow upon the desk were maps and doc.u.ments in profusion. And in the corner he could make out the lines of an iron-bound chest or box. They had made no mistake. Unless in the possession of Von Schlichter it was here that the Chinese treaty would be found.

"All right," whispered Crabb. "An old-fashioned padlock, too."

Crabb tried the window. It was locked. He took something from one of the pockets of his coat and reached up to the middle of the sash. There was a sound like the quick shearing of linen which sent the blood back to Burnett's heart. In the still night it seemed to come back manifold from the wings of the buildings opposite. They paused again. A slight crackling of broken gla.s.s, and Crabb's long fingers reached through the hole and turned the catch. In a moment they were in the room.

The intangible and Quixotic had become a latter-day reality. Burnett's spirits rose. He did not lack courage, and here was a situation which spurred him to the utmost.

Instinctively he closed the inside shutters behind him. From the alley the pair would not have presented an appearance which accorded with the quiet splendor of the room. He found himself peering around, his ears straining for the slightest sound.

A glance revealed the dispatch-box, heavy, squat and phlegmatic, like its owner. Crabb had tiptoed over to the door of the adjoining room.

Burnett saw the eyes dilate and the warning finger to his lips.

From the inner apartment, slowly and regularly, came the sound of heavy breathing. There, in a broad armchair by the foot of the bed, sprawled the baron's valet, in stertorous sleep. His mouth was wide open, his limbs relaxed. He had heard nothing.

"Quick," whispered Crabb; "your bandanna around his legs."

Burnett surprised himself by the rapidity and intelligence of his collaboration. A handkerchief was slipped into the man's mouth, and before his eyes were fairly opened he was gagged and bound hand and foot by the cord from the baron's own dressing gown.

From a pocket Crabb had produced a revolver, which he flourished significantly under the nose of the terrified man, who recoiled before the dark look which accompanied it.

Crabb seemed to have planned exactly what to do. He took a bath towel and tied it over the man's ears and under his chin. From the bed he took the baron's sheets and blankets, enswathing the unfortunate servant until nothing but the tip of his nose was visible. A rope of suspenders and cravats completed the job.

The Baron Arnim's valet, to all the purposes of usefulness in life, was a bundled mummy.

"Phew!" said Crabb, when it was done. "Poor devil! But it can't be helped. He mustn't see or know. And now for it."

Crabb produced a bunch of skeleton keys and an electric bull's-eye. He tried the keys rapidly. In a moment the dispatch-box was opened and its contents exposed to view.

"Carefully now," whispered Crabb. "What should it look like?"

"A foolscap-shaped thing in silk covers with dangling cords," said Ross.

"There, under your hand."

In a moment they had it out and between them on the desk. There it was, in all truth, written in two columns, Chinese on the one side, French on the other.

"Are you sure?" said Crabb.

"Sure! Sure as I'm a thief in the night!"

"Then sit and write, man. Write as you never wrote before. I'll listen and watch Rameses the Second."

In the twenty minutes during which Burnett fearfully wrote, Crabb stood listening at the doors and windows for sounds of servants or approaching carriages. The man swaddled in the sheets made a few futile struggles and then subsided. Burnett's eyes gleamed. Other eyes than his would gleam at what he saw and wrote. When he finished he closed the doc.u.ment, removed all traces of his work, replaced it in the iron box and shut the lid. He dropped the precious sheets into an inner pocket and was moving toward the window when Crabb seized him by the arm. There was a step in the hallway without, and the door opened. There, stout and grizzled, his walrus mustache bristling with surprise, in all the distinction of gold lace and orders, stood Baron Arnim.

CHAPTER V

For a moment there was no sound. The burglars looked at the Baron and the Baron looked at the burglars, mouths and eyes open alike. Then, even before Crabb could display his intimidating revolver, the German had disappeared through the door screaming at the top of his lungs.

"Quick! Out of the window!" said Crabb, helping Burnett over the sill.

"Down you go--I'll follow. Don't fall. If you miss your footing, we're ruined."

Burnett scrambled out, over the coping and down the ladder, Crabb almost on his fingers. But they reached the yard in safety and were out in the alley running in the shadow of the fence before a venturesome head stuck forth from the open window and a revolver blazed into the vacant air.

"The devil!" said Crabb. "They'll have every copper in the city on us in a minute. This way." He turned into a narrow alley at right angles to the other. "Off with the coat as you go--now, the mustache and grease paint. Take your time. Into this sewer with the coats. So!"

Two gentlemen in light topcoats, one in a cap, the other in a hat, walked up N street arm in arm, thickly singing. Their shirt fronts and hair were rumpled, their legs were not too steady, and they clung affectionately to each other for support and sang thickly.

A window flew up and a tousled head appeared.

"Hey!" yelled a voice. "Burglars in the alley!"

"Burglars!" said one of the singers; and then: "Go to bed. You're drunk."

More sounds of windows, the blowing of night whistles and hurrying feet.

Still the revelers sang on.

A stout policeman, clamorous and bellicose, broke in.

"Did you see 'em? Did you see 'em?" he cried, glaring into their faces.

Bleary eyes returned his look.

"W-who?" said the voices in unison.
