siren droned dismally over his head. Fog lay deep about the ship. The washing of the waves and dripping of water on the decks was depressing. It seemed to be getting thicker. Four stanchions ahead, the mist was noticeable. He found that he could count five, six, seven… The eighth was indefinite. But a bar materialized in the fog before him, and the grayness drew away before him and closed in behind. When he was at the forward end of the promenade, looking down upon the forecastle deck, he was isolated. He heard footsteps some distance overhead. The watch officer up on the bridge. Bell glanced up and saw him as an indistinct figure. He waited until the officer paced over to the opposite side of the bridge. The air throbbed and shook with the roaring of the siren.
Bell slipped over the edge of the rail and swung swiftly down the little ladder of iron bars set into the ship's structure. In seconds he had landed, and was down upon that terra incognita of all passengers, the deck reserved for the use of the crew.
A mast loomed overhead, with its heavy, clumsy derrick-booms. A winch was by his side. Oddments of deck machinery, inexplicable to a landsman, formed themselves vaguely in the mist. The fog was thicker, naturally, since the deck was closer to the water's edge.
"Hey!" growled a voice close beside him. "Passengers ain't allowed down here."
An unshaven, soot-smeared figure loomed up. Bell could not see the man save as a blur in the mist, but he said cheerfully:
"I know it, but I wanted to look. Seafaring's a trade I'd like to know something about."
The figure grunted. Bell had just given his word of honor that he wasn't a member of the Secret Service. He wasn't. But he was in the Trade – which has no official existence anywhere. And the use of the word in his first remark was a recognition signal.
"What is your trade, anyways?" growled the figure skeptically.
"I sharpen serpents' teeth from time to time," offered Bell amiably. He recognized the man, suddenly. "Hullo, Jamison, you look like the devil."
Jamison drew nearer. He grunted softly.
"I know it. Listen closely, Bell. Your job is getting some information from Canalejas, Minister of War in Rio. He sent word up to Washington that he'd something important to say. It isn't treachery to Brazil, because he's a decent man. Seven Secret Service men have disappeared in South America within three months. They've found the eighth, and he's crazy. Something has driven him mad, and they say it's a devilish poison. He's a homicidal maniac, returning to the United States in a straight-jacket. Canalejas knows what's happened to the Service men. He said so, and he's going to tell us. His daughter brought the news to Washington, and then instead of going on to Europe as she was supposed to do, she started back to Rio. You're to get this formation and pass it on to me, then try to keep your skin whole and act innocent. You were picked out because, as a State Department man, hell could be raised if you vanished. Understand?"
Bell nodded.
"Something horrible is going on. Secret Service can't do anything. The man in Asunción isn't dead – he's been seen – but he's cut loose. And Service men don't often do that. He don't report. That means the Service code may have been turned over, and hell to pay generally. It's up to the Trade."
"I've got it," said Bell. "Here are two items for you. Miss Canalejas just said she suspected I was Secret Service. I convinced her I wasn't. She says she has important information for a Service man."
The brawny figure of the stoker growled.
"Damn women! She was told somebody'd be sent to see her father. She was shown a recognition-knot with the outsider's variation. Given one, for father. That'll identify you to him. But she shouldn't have talked. Now, be careful. As nearly as we know, that chap in the straight-jacket was given some poison that drove him insane. There are hellish drugs down there. Maybe the same thing happened to others. Look out for yourself, and give me the information Canalejas gives you as quickly as God will let you. If anything happens to you, we want the stuff to get back. Understand?"
"Of course," said Bell. He carefully did not shiver as he realized what Jamison meant by anything happening to him. "The other item is that Ortiz, ex-Minister of the Interior of the Argentine, is scared to death about something. Sending radios right and left."
"Umph," growled Jamison. "One of our men vanished in Buenos Aires. Watch him. You're friendly?"
"Yes."
"Get friendlier. See what he's got. Now shoo."
Bell swung up the ladder again. Mist opened before him and closed again behind. He climbed over the rail to the promenade deck, and felt a little flare of irritation. There was a figure watching him.
He slipped to the deck and grinned sheepishly at Paula Canalejas. She stood with her hands in the pockets of her little sport coat, regarding him very gravely.
"I suppose," said Charley Bell sheepishly, "that I look like a fool. But I've always wanted to climb up and down that ladder. I suppose it's a survival from the age of childhood. At the age of seven I longed to be a fireman."
"I wonder," said Paula quietly. "Mr. Bell" – she stepped close to him – "I am taking a desperate chance. For the sake of my father, I wish certain things known. I think that you are an honorable man, and I think that you lied to me just now. Go and see Senor Ortiz. Your government will want to know what happens to him. Go and see him quickly."
Bell felt the same flare of irritation as before. Women do not follow rules. They will not follow rules. They depend upon intuition, which is sometimes right, but sometimes leads to ungodly errors. Paula was right this time, but she could have been wholly and hopelessly wrong. If she had talked to anyone else…
"My child," said Bell paternally – he was at least two years older than Paula – "you should be careful. I did not lie to you just now. I am not Secret Service. But I happen to know that you have a tiny piece of string to give your father, and I beg of you not to show that to anyone else. And – well – you are probably watched. You must not talk seriously to me!"
He lifted his hat and started astern. He was more than merely irritated. He was almost frightened. Because the Trade, officially, does not exist at all, and everybody in the Trade is working entirely on his own; and because those people who suspect that there is a Trade and dislike it are not on their own, but have plenty of resources behind them. And yet it is requisite that the Trade shall succeed in its various missions. Always.
The Government of the United States, you understand, will admit that it has a Secret Service, which it strives to identify solely with the pursuit of counterfeiters, postal thieves, and violators of the prohibition laws. Strongly pressed, it will admit that some members of the Secret Service work abroad, the official explanation being that they work abroad to forestall smugglers. And at a pinch, and in confidence, it may concede the existence of diplomatic secret agents. But there is no such thing as the Trade. Not at all. The funds which members of the Trade expend are derived by very devious bookkeeping from the appropriations allotted to an otherwise honestly conducted Department of the United States Government.
Therefore the Trade does not really exist. You might say that there is a sort of conspiracy among certain people to do certain things. Some of them are government officials, major and minor. Some of them are private citizens, reputable and otherwise. One or two of them are in jail, both here and abroad. But as far as the Government of the United States is concerned, certain fortunate coincidences that happen now and then are purely coincidences. And the Trade, which arranges for them, does not exist. But it has a good many enemies.
The fog-horn howled dismally overhead. Mist swirled past the ship, and an oily swell surged vaguely overside and disappeared into a gray oblivion half a ship's length away. Bell moved on toward the stern. It was his intention to go into the smoking-room and idle ostentatiously. Perhaps he would enter into another argument with that Brazilian air pilot who had so much confidence in Handley-Page wing-slots. Bell had, in Washington, a small private plane that, he explained, had been given him by a wealthy aunt, who hoped he would break
