old Chinese on a corner directed him to Jackson Street, and he climbed its steep sidewalk until he reached the shop of Wong Ching. The brightly lighted window was filled with Swatow cups and bowls, a rather beautiful display, but evidently during this holiday season the place was not open for business, for the curtains on the door were drawn. Chan rattled the latch for a full minute, but no one came.
He crossed the street, and took up a post in a dark doorway opposite. Sooner or later his summons would be answered. On a near-by balcony a Chinese orchestra was playing, the whanging flute, the shrill plink of the moon-kwan, the rasping cymbals and the drums filled the night with a blissful dissonance. Presently the musicians ceased, the din died away, and Chan heard only the click of American heels and the stealthy swish of felt slippers passing his hiding place.
In about ten minutes the door of Wong Ching's shop opened and a man came out. He stood looking cautiously up and down the dim street. A thin man in an overcoat which was buttoned close about him—a chilly-seeming man. His hat was low over his eyes, and as a further means of deceit he wore dark spectacles. Charlie Chan permitted a faint flash of interest to cross his chubby face.
The chilly man walked briskly down the hill, and stepping quickly from the doorway, Chan followed at a distance. They emerged into Grant Avenue; the dark-spectacled one turned to the right. Still Chan followed; this was child's play for him. One block, two, three. They came to a cheap hotel, the Killarney, on one of Grant Avenue's corners, and the man in the overcoat went inside.
Glancing at his watch, Chan decided to let his quarry escape, and turned in the direction of Union Square. His mind was troubled. "This much even a fool could grasp," he thought. "We move toward a trap. But with eyes open—with eyes keenly open."
Back in his tiny hotel room, he restored to his inexpensive suitcase the few articles he had previously removed. Returning to the desk, he found that his trunk had reached the hotel but had not yet been taken upstairs. He arranged for its storage until his return, paid his bill and sitting down in a great leather chair in the lobby, with his suitcase at his feet, he waited patiently.
At precisely ten-thirty Bob Eden stepped inside the door of the hotel and beckoned. Following the young man to the street, Chan saw a big limousine drawn up to the curb.
"Jump in, Mr. Chan," said the boy, taking his bag. As the detective entered the darkened interior, Alexander Eden greeted him from the gloom. "Tell Michael to drive slowly—I want to talk," called the older man to his son. Bob Eden spoke to the chauffeur, then leaped into the car and it moved off down Geary Street.
"Mr. Chan," said the jeweler in a low voice, "I am very much disturbed."
"More events have taken place," suggested Chan.
"Decidedly," Eden replied. "You were not in the room this afternoon when I spoke of a telephone call I had received from a pay-station at Sutter and Kearny Streets." He repeated the details. "This evening I called into consultation Al Draycott, head of the Gale Detective Agency, with which I have affiliations. I asked him to investigate and, if possible, find that man in the overcoat Bob saw at the dock. An hour ago he reported that he had located our man with no great difficulty. He has discovered him—"
"At the Killarney Hotel, perhaps, on Grant Avenue," suggested Chan, dissembling a deep triumph.
"Good lord," gasped Eden. "You found him, too. Why—that's amazing—"
"Amazing luck," said Chan. "Please pardon rude interruption. Will not occur again."
"Well, Draycott located this fellow, and reports that he is Shaky Phil Maydorf, one of the Maydorf brothers, as slick a pair of crooks as ever left New York for their health. The fellow suffers from malaria, I believe, but otherwise he is in good form and, it seems, very much interested in our little affairs. But Mr. Chan—your own story—how in the world did you find him too?"
Chan shrugged. "Successful detective," he said, "is plenty often man on whom luck turns smiling face. This evening I bask in most heart-warming grin." He told of his visit to Chan Kee Lim, of the telephone call to the desert from Wong's bowl shop, and of his seeing the man in the overcoat leaving the shop. "After that, simple matter to hound him to hotel," he finished.
"Well, I'm more disturbed than ever," Eden said. "They have called the caretaker away from Madden's ranch. Why? I tell you I don't like this business—"
"Nonsense, father," Bob Eden protested. "It's rather interesting."
"Not to me. I don't welcome the attention of these Maydorfs—and where, by the way, is the other one? They are not the modern type of crook—the moron brand that relies entirely on a gun. They are men of brains—old-fashioned outlaws who are regarded with respect by the police whom they have fought for many years. I called Sally Jordan and tried to abandon the whole proceeding—but that son of hers. He's itching to get the money, and he's urging her to go ahead. So what can I do? If it was any one else I'd certainly drop out of the deal—but Sally Jordan—well, she's an old friend. And as you said this afternoon, Mr. Chan, there is such a thing as loyalty in the world. But I tell you I'm sending you two down there with the deepest reluctance."
"Don't you worry, dad. It's going to be great fun, I'm sure. All my life I've wanted to be mixed up in a good exciting murder. As a spectator, of course."
"What are you talking about?" the father demanded.
"Why, Mr. Chan here is a detective, isn't he? A detective on a vacation. If you've ever read a mystery story you know that a detective never works so hard as when he's on a vacation. He's like the postman who goes for a long walk on his day off. Here we are, all set. We've got our bright and shining mark, our millionaire—P.J. Madden, one of the most famous financiers in America. I tell you, poor P.J. is doomed. Ten to one Mr. Chan and I will walk into that ranch house and find him dead on the first rug we come to."
"This is no joking matter," Eden rebuked severely. "Mr. Chan—you seem to be a man of considerable ability. Have you anything to suggest?"
Charlie smiled in the dark car. "Flattery sounds sweet to any ear," he remarked. "I have, it is true, inclination for making humble suggestion."
"Then, for heaven's sake, make it," Eden said.
"Pray give the future a thought. Young Mr. Eden and I walk hand in hand, like brothers, on to desert ranch. What will spectator say? Aha, they bring pearls. If not, why come together for strength?"
"Absolutely true," Eden agreed.
"Then why travel side by side?" Charlie continued. "It is my humble hint that Mr. Bob Eden arrive alone at ranch. Answering all inquiries he says no, he does not carry pearls. So many dark clouds shade the scene, he is sent by honorable father to learn if all is well. When he is sure of that, he will telegraph necklace be sent at once, please."
"A good idea," Eden said. "Meanwhile—"
"At somewhat same hour," Chan went on, "there stumble on to ranch weary old Chinese, seeking employment. One whose clothes are of a notable shabbiness, a wanderer over sand, a what you call—a desert rat. Who would dream that on the stomach of such a one repose those valuable Phillimore pearls?"
"Say—that's immense," cried Bob Eden enthusiastically.
"Might be," admitted Chan. "Both you and old Chinese look carefully about. If all is well, together you approach this Madden and hand over necklace. Even then, others need not know."
"Fine," said the boy. "We'll separate when we board
