THE MYSTERY OF THE CHICAGO RIVER

Johnny Thompson dodged around a corner on West Ohio street, then walked hurriedly down Wells street. At a corner of the building which shadowed the river from the north he paused and listened; then with a quick wrench, he tore a door open, closed it hastily and silently, and was up the dusty stairs like a flash. At the top he waited and listened, then turning, made his way up two other flights, walked down a dark corridor, turned a key in a lock, threw the door open, closed it after him, scratched a match, lighted a gas lamp, then uttered a low "Whew!" at the dust that had accumulated everywhere.

Brushing off a chair, he sat down. For a few moments he sat there in silent reflection. Then rising, he extinguished the light, threw up the sash, unhooked some outer iron shutters, sent them jangling against the brick wall, and drawing his chair to the window, stared reflectively down into the sullen, murky waters of the river. At last he was back in Chicago!

The time had been when the fact that Johnny Thompson occupied this room was no secret to anyone who really wanted to know. Johnny had roomed here when he first came to Chicago as a boy, working for six dollars a week. When, in the years that followed, it had been discovered that Johnny was quick as a bobcat and packed a wallop; when Johnny began making easy money, and plenty of it, he had stuck to the old room that overlooked the river. When he had heard his country's call to go to war, he had paid three years' rent on the room and had locked the door. If he never came back, all good and well. If he did return, the old room would be waiting for him, the room and the river. Now here he was once more.

The river! The stream had always held a great fascination for him. Johnny had seen other rivers but to him none of them quite came up to the old Chicago. In its silent, sullen depths lay power and mystery. The Charles River of Boston Johnny had seen, and called it a place of play for college boys. The Seine of Paris was a thing of beauty, not of power. The Spokane was a noisy blusterer. But the old Chicago was a grim and silent toiler. It bore on its waters great scows, lake boats, snorting, smoking tugs, screaming fire boats and police boats. Then, too, it was a river of mysteries. Down into its murky depths no eye could peer to discover the hidden and mysterious burdens which it carried away toward the Father of Waters.

Yes, give Johnny the room by the old Chicago! It was dusty and grim; but tomorrow he would clean it thoroughly. Just now he wished merely to sit here and think for an hour.

The time had been when Johnny had not cared who saw him enter this haven; but to-day things were different. Since he had got into this affair with the Russian and his band he had had a feeling that he was being constantly watched.

There was little wonder at this, for did he not carry on his person forty thousand dollars' worth of rare gems? And did they not belong to someone else?

"To whom?" Johnny said the words aloud as he thought of it.

His mind turned to his Japanese comrades, the girl and the man. He had told neither of them about the diamonds. Perhaps he should have done so, and yet he felt a strange reticence in the matter.

He was to meet Hanada at eight o'clock. Hanada had never told him why they were pursuing the Russian; why he could not be killed in Siberia; why he must not be killed or arrested if seen now, until he, Hanada, said the word. He had not told why he thought that the Secret Service men had committed a blunder in offering a reward for the Russian's capture.

As Johnny thought of it he wondered if he were a fool for sticking to this affair into which he had been so blindly led. He had not shown himself to his old boss or to Mazie. To them he was dead. He had looked up the official record that very morning and had seen that he was reported "Missing in Vladivostok; probably dead."

Should he stick to the Russian's trail, a course which might lead to his death, or should he take the diamonds to a customs office and turn them in as smuggled goods, then tell Hanada he was off the hunt, was going back to his old job and Mazie? That would be a very easy thing to do; and to stick was fearfully hard. Yet the words of his long time friend, "Get that man, or it will be worse for your country and mine," still rang in his ears. Was it his patriotic duty to stick?

And if he decided to go on with it, should he go to Hanada and ask for a showdown, all cards on the table; or should he trust him to reveal the facts in the case little by little or all at once, as seemed wise to him? Well, he should see.

Then, for a half hour, Johnny gave himself over to the wild, boyish reveries which the city air and the lights flickering on the water awakened. At the end of that half hour he put on his hat and went out. He was to meet Hanada on the Wells street bridge. Where the Japanese was staying he did not know, but that it was with some fellow countrymen he did not doubt. Cio-Cio-San was staying with friends, students at the University. It had been arranged that the three of them should meet at odd times and various places to discuss matters relating to their dangerous mission. In this way they hoped to throw members of the band of Radicals off their tracks.

Their conversation that night came to little. Hanada had found no trace of the Russian, nor had he come into contact with any other important Radicals since reaching Chicago. Johnny's report was quite as brief. Hanada showed no inclination to reveal more regarding the matter, and Johnny did not question him. He had fully determined to see the thing through, cost what it might.

It was after a roundabout walk through the deserted streets of the business section of the city that they came to South Water street. This street, the noisiest and most crowded of all Chicago at certain hours, was now as silent and deserted as a village green at midnight. Here a late pedestrian hurried down its narrow walk: there some boatman loitered toward his craft in the river. But for these the street was deserted.

And it was here, of all places, that they experienced the first thrill of the night. A heavy step sounded on the pavement around the corner. The next instant a man appeared walking toward them. His face was obscured by shadows, but there was no mistaking that stride.

"That's our man," whispered Johnny.

"The Russian?" questioned Hanada in equally guarded tones.

There was not time for another word, for the man, having quickened his pace was abreast of them, past them and gone.

"I don't know. Couldn't see his face," whispered the Jap.

"Quick!" urged Johnny; "there's a short cut, an alley. We can meet him again under the arc light."

Down a dark alley they dashed. Crashing into a broken chicken crate, then sprinting through an open court, they came out on another alley, and then onto a street.

They had raced madly, but now as they came up short, panting, they saw no one. The man had disappeared.

Suddenly they heard steps on the cross street.

"Turned the corner," panted Johnny. "C'mon!"

Again they dashed ahead, slowing only as they reached the other street.

Sure enough, halfway down the block they saw their man. He was walking rapidly toward the bridge. Quickening their pace they followed.

Distinctly they saw the man go upon the bridge. Very plainly they heard every footstep on the echoing planks. Then, just as they were about to step upon the bridge, the footsteps ceased.

"Sh!" whispered Johnny, bringing his friend to a halt. "He's stopped; maybe laying for us."

For a minute they stood there. The lapping of the water was the only sound till, somewhere in the distance an elevated train rattled its way north.

"C'mon," said Johnny. "We've met that bird in worse places than this; we can meet him again."

But they did not meet him, although they walked the full length of the bridge. There was not a place on the whole structure where a man could hide, but they searched it thoroughly. Then Johnny searched the sides, the abutments. He sent the gleam of his powerful flashlight into the dark depths beneath, but all to no purpose. The man was gone.

"Humph!" said Johnny.

"Hisch!" breathed Hanada.

"Well, all I have to say," observed Johnny presently, "is that if the old Chicago River has that fellow, he'll be cast ashore. The good old Chicago doesn't associate with any such."

They stood there leaning on the wooden railing debating their next move, when a shot rang out. Instantly they dropped to the floor of the bridge. A bullet whizzed over their heads, then another and another. After that silence.

"Get you?" whispered Johnny.

"No. You?"

"Nope."

Then a long finger of light came feeling its way along the murky waters to rest on the bridge.

With a sigh of relief, Johnny saw that it came from a police-boat down stream. The light felt its way back and forth, back and forth across the river, then up to the bridge and across that. It came to rest as it glared into their eyes. It blinked one, two, three times, then went out.

"I'm glad they didn't hold it on us," breathed Johnny. "In that light anybody that wanted to could get a bead on us."

Hearing heavy, hurrying footsteps approaching, they stood up well back against the iron braces.

"Police!" whispered Johnny.

"You fellows shoot?" demanded one of the policemen as they came up and halted before the two boys.

"Nope," Johnny answered.

"No stallin' now."

"Search us," Johnny suggested. "The shots were fired at us, though where from, blessed if I know. Came right out of space. We'd just searched the bridge from end to end. Not a soul on it."

"What'd y' search it fer?"

"A man."

"W'at man?"

"That's it," Johnny evaded. "We wanted to know who he was."

The policemen conversed with one another in low tones for a moment.

"One of the bullets struck a cross-arm; I heard it," suggested Johnny. "You can look at that if it'll be any comfort to you."

The policeman grunted, then following Johnny's flashlight, examined the spot where the bullet had flaked the paint from the bridge iron.

"Hurum!" he grumbled. "That's queer. Bullet slid straight up the iron when it struck. Ordinarily that'd mean she was shot square against it from below and straight ahead, but that can't be, fer that brings her comin' direct out of the river, which ain't human, nor possible. There wasn't a boat nor a barge nor even a plank on the river when the searchlight flashed from the gray prowler; was there, Mike?"

"Not even a cork," said Mike.

"Well, anyway, that clears youse guys," grunted the leader. "Now you better beat it."

Bidding Hanada good night, Johnny walked across the bridge, around four blocks, then made a dash for his room. There was dust on his blankets, but he could shake it off. Anyway, he probably would not sleep much that night. Probably he would spend most of the night sitting by the window, listening to the lap of the waters of the old river and trying to solve the strange problem of the bullets fired apparently from the depths of the stream.
