From the Blue Dragon to Chang Foo’s was not far; and Jimmie Dale covered the distance in well under five minutes.  Chang Foo’s was just a tea merchant’s shop, innocuous and innocent enough in its appearance, blandly so indeed, and that was all—­outwardly; but Jimmie Dale, as he reached his destination, experienced the first sensation of uplift he had known that night, and this from what, apparently, did not in the least seem like a contributing cause.

“Luck!  The blessed luck of it!” he muttered grimly, as he surveyed the sight-seeing car drawn up at the curb, and watched the passengers crowding out of it to the ground.  “It wouldn’t have been as easy to fool old Chang as it was that fellow back at the Dragon—­and, besides, if I can work it, there’s a better chance this way of getting out alive.”

The guide was marshalling his “gapers”—­some two dozen in all, men and women.  Jimmie Dale unostentatiously fell in at the rear; and, the guide leading, the little crowd passed into the tea merchant’s shop.  Chang Foo, a wizened, wrinkled-faced little Celestial, oily, suave, greeted them with profuse bows, chattering the while volubly in Chinese.

The guide made the introduction with an all-embracing sweep of his hand.

“Chang Foo—­ladies and gentlemen,” he announced; then held up his hand for silence.  “Ladies and gentlemen,” he said impressively, “this is one of the most notorious, if not the most notorious dive in Chinatown, and it is only through special arrangement with the authorities and at great expense that the company is able exclusively to gain an entree here for its patrons.  You will see here the real life of the Chinese, and in half an hour you will get what few would get in a lifetime spent in China itself.  You will see the Chinese children dance and perform; the Chinese women at their household tasks; the joss, the shrine of his hallowed ancestors, at which Chang Foo here worships; and you will enter the most famous opium den in the United States.  Now, if you will all keep close together, we will make a start.”

In spite of his desperate situation, Jimmie Dale smiled a little whimsically.  Yes; they would see it all—­upstairs!  The same old bunk dished out night after night at so much a head—­and the nervous little schoolma’am of uncertain age, who fidgeted now beside him, would go back somewhere down in Maine and shiver while she related her “wider experiences” in tremulous whispers into the shocked ears of envious other maiden ladies of equally uncertain age.  The same old bunk—­and a profitable one for Chang Foo for more reasons than one.  It was dust in the eyes of the police.  The police smiled knowingly at mention of Chang Foo.  Who should know, if they didn’t, that it was all harmless fake, all bunk!  And so it was—­upstairs!
