"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 the train. If you're in doubt at any time, just keep your eye on me, and tag along. We're due in Barstow tomorrow at one-fifteen, and there's a train to Eldorado at three-twenty, which arrives about six. I'm taking it, and you'd better do the same. One of my newspaper friends here has given me a letter to a fellow named Will Holley, who's editor of a little paper at Eldorado. I'm going to invite him to have dinner with me, then I'll drive out to Madden's. You, of course, will get out some other way. As somebody may be watching us, we won't speak on our journey. Friends once, but strangers now. That's the idea, isn't it?"
"Precisely the notion," agreed Chan.
The car had stopped before the ferry building. "I have your tickets here," Alexander Eden said, handing over a couple of envelopes. "You have lower berths, in the same car, but at different ends. You'll find a little money there for expenses, Mr. Chan. I may say that I think your plan is excellent—but for heaven's sake, be careful, both of you. Bob, my boy—you're all I've got. I may have spoken harshly to you, but I—I—take care of yourself."
"Don't you worry, dad," Bob Eden said. "Though you'll never believe it, I'm grown up. And I've got a good man with me."
"Mr. Chan," Eden said. "Good luck. And thank you a thousand times."
"Don't talk about it," smiled Charlie. "Happiest walk of postman's life is on his holiday. I will serve you well. Good-bye."
He followed Bob Eden through the gates and on to the ferryboat. A moment later they had slipped out upon the black waters of the harbor. The rain was gone, the sky spattered with stars, but a chill wind blew through the Gate. Charlie stood alone by the rail; the dream of his life had come true; he knew the great mainland at last. The flaming ball atop the Ferry Building receded; the yellow lamps of the city marched up the hills and down again. He thought of the tiny island that was his home, of the house on Punchbowl Hill where his wife and children patiently awaited his return. Suddenly he was appalled at the distance he had come.
Bob Eden joined him there in the dark, and waved his hand toward the glow in the sky above Grant Avenue. "A big night in Chinatown," he said.
"Very large night," agreed Chan. "And why not? Tomorrow is the first day of the new year. Of the year 4869."
"Great Scott," smiled Eden. "How time flies. A Happy New Year to you."
"Similar one to you," said Chan.
The boat plowed on. From the prison island of Alcatraz a cruel, relentless searchlight swept at intervals the inky waters. The wind was bitter now.
"I'm going inside," shivered Bob Eden. "This is goodbye, I guess."
"Better so," admitted Charlie. "When you are finally at Madden's ranch, look about for that desert rat."
Alone, he continued to stare at the lamps of the city, cold and distant now, like the stars.
"A desert rat," he repeated softly, "with no fondly feeling for a trap."
Chapter IV. The Oasis Special
Dusk was falling in the desert town of Eldorado when, on Friday evening, Bob Eden alighted from the train at a station that looked like a little red schoolhouse gone wrong. His journey down from San Francisco to Barstow had been quite without incident. At that town, however, a rather disquieting thing had happened. He had lost all trace of Charlie Chan.
It was in the Barstow lunch-room that he had last seen the detective from the islands, busy with a cup of steaming tea. The hour of three-twenty and the Eldorado train being some distance off, he had gone for a stroll through the town. Returning about three, he had looked in vain for the little Chinese policeman. Alone he had boarded the train and now, as he stared up and down the dreary railroad tracks, he perceived that he had been the only passenger to alight at this unpromising spot.
Thinking of the fortune in "undigestible" pearls on the detective's person, he was vaguely alarmed. Had Chan met with some unfortunate accident? Or perhaps who could say? What did they really know about this Charlie Chan? Every man is said to have his price, and this was an overwhelming temptation to put in the way of an underpaid detective from Honolulu. But no—Bob Eden recalled the look in Chan's eyes when he had promised Sally Jordan to guard those pearls well. The Jordans no doubt had good reason for their faith in an old friend. But suppose Shaky Phil Maydorf was no longer in San Francisco—
Resolutely Bob Eden put these thoughts aside and, rounding the station, entered a narrow strip of ground which was, rather pathetically, intended for a park. February had done its worst, and up above the chill evening wind from the desert blew through the stark branches of Carolina poplars and cottonwoods. Crossing a gravel path almost hidden by a mass of yellow leaves, he stood on the curb of the only pavement in Eldorado.
Against the background of bare brown hills, he saw practically the entire town at a glance. Across the way a row of scraggly buildings proclaimed yet another Main Street—a bank, a picture theater, the Spot Cash Store, the News Bureau, the post-office, and towering above the rest, a two-story building that announced itself as the Desert Edge Hotel. Eden crossed the street, and threading his way between dusty automobiles parked head-on at the curb, approached the door of the latter. On the double seat of a shoe-shining stand two ranchers lolled at ease, and stared at him with mild interest as he went inside.
An electric lamp of modest candle-power burned above the desk of the Desert Edge, and a kindly old man read a Los Angeles paper in its dim company.
"Good evening," said Bob Eden.
"Evenin'," answered the old man.
"I wonder if I might leave this suitcase in your check-room for a while?" the boy inquired.
"Check-room, hell," replied the old man. "Just throw her down anywhere. Ain't lookin' fer a room, I suppose. Make you a special rate."
"No," said Eden. "I'm sorry."
"'Sall right," answered the proprietor. "Not many are."
"I'd like to find the office of the Eldorado Times," Eden informed him.
"Round corner on First," murmured the old man, deep in his pink newspaper again.
Bob Eden went to the corner, and turned off. His feet at once left Eldorado's solitary sidewalk for soft crunching sand. He passed a few buildings even meaner than those on Main Street, a plumber's shop, a grocer's, and came to a little yellow shack which bore on its window the fading legend: "The Eldorado Times. Job Printing Neatly Done." There was no light inside, and crossing a narrow, dilapidated porch, he saw a placard on the door. Straining his eyes in the dusk, he read:
"Back
