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.
