With a cry of dismay the man ran toward it, but Roddy was before him. As the note had left his hand his fingers had touched upon heavy, waxen seals.

In an instant he had retrieved the note, and, followed eagerly by the man, carried it to the light of a gas lamp. The envelope was not illuminating, the sealing-wax was stamped with no crest or initials, the handwriting was obviously disguised.

After observing that from the shadow the man still watched him, while at the same time he kept an anxious lookout up and down the street, Roddy opened the note. It read: “You have come to Curaçao for a purpose. One who has the success of that purpose most at heart desires to help you. To-morrow, just before sunrise, walk out the same road over which you drove to-day. Beyond the Café Ducrot the bearer of this letter will wait for you with a led horse. Follow him. If you think he is leading you into danger, order him to ride in advance, and cover him with your revolver. If you will come, say to the bearer, ‘Vengo,’ if not, ‘No Vengo.’ He has orders not to reply to any question of yours. If you speak of this to others, or if the bearer of this suspects you have arranged for others to follow you, he will only lead you back to your hotel, and your chance to right a great wrong will have passed.”

There was no signature. But as though it were an afterthought, at the bottom of the page was written, “Adventures are for the adventurous.”

Standing well in the light of the street lamp, with his back to the houses, with his face toward the waiting messenger, Roddy read the letter three times. But after the first reading his eyes neglected the body of the note and raced to the postscript. That was the line that beckoned and appealed; to him it seemed that whoever wrote the letter doubted he would come to the rendezvous, and was by that line enticing him, mocking him, daring him to refuse. It held forth both a promise and a challenge.

As to who the writer of the note might be, there were in Roddy’s mind three explanations. He considered them hastily. Peter was the author of the note, and it was a poor joke intended to test him. It was a genuine offer from some one who had guessed the object of his visit to Curaçao and honestly wished to be of service. It came from the man in the mask and his associates, who, resenting his interference of the morning, had pleasant thoughts of luring him down a lonely road and leaving him lying there. Which of the three suppositions might be correct it was impossible to know, but the postscript decided him. He beckoned to the messenger, and the man ran eagerly forward. “I will come,” said Roddy. The man smiled with pleasure, bowed to him, and dived into the darkness. As he ran down the street Roddy stood listening until the soft patter of the sandals had ceased, and then slowly returned to the hotel.

For an hour, still speculating as to who his anonymous friend might be, he stood, smoking, upon the balcony. On the quay below him a negro policeman dozed against a hawser-post. A group of cargadores, stretched at length upon stacks of hides, chattered in drowsy undertones. In the moonlight the lamps on the fishing-boats and on the bridge, now locked against the outside world, burned mistily, and the deck of the steamer moored directly below him was as deserted and bare, as uncanny and ghostlike, as the deck of the ship of the Ancient Mariner. Except for the chiming of ships’ bells, the whisper of the running tide, and the sleepy murmur of the longshoremen, the town of Willemstad was steeped in sleep and silence. Roddy, finding he could arrive at no satisfactory explanation of the note, woke the night porter, and telling that official he was off before daybreak to shoot wild pigeons, and wanted his coffee at that hour, betook himself to his cot. It seemed as though he had not twice tossed on the pillow before the night-watchman stood yawning at his side.

Roddy and Peter occupied adjoining rooms, and the door between the two was unlocked. When Roddy had bathed, dressed, and, with a feeling of some importance, stuck his revolver into his pocket, he opened the door, and, still suspicious that his faithful friend was sending him on a wild-goose chase, for a few moments stood beside his bed. But Peter, deep in the sleep of innocence, was breathing evenly, stentoriously. Not without envying him the hours of rest still before him, Roddy helped himself to Peter’s revolver, left him a line saying it was he who had borrowed it, and went out into the dark and empty streets.

Half awake and with his hunger only partially satisfied, Roddy now regarded his expedition with little favor. He reverted strongly to the theory that some one was making a fool of him. He reminded himself that if in New York he had received such a note, he either would have at once dismissed it as a hoax or turned it over to the precinct station-house. But as the darkness changed to gray, and the black bulk of the Café Ducrot came into view, his interest quickened. He encouraged himself with the thought that while in New York the wording of the note would be improbable, hysterical, melodramatic, in hot, turbulent Venezuela it was in keeping with the country and with the people.

Since setting forth from the hotel a half hour had passed, and as he left the Café Ducrot behind him the night faded into the gray-blue mist of dawn. Out of the mist, riding slowly toward him, mounted on one pony and leading another, Roddy saw the man who on the night before had brought him the letter. He was leaning forward, peering through the uncertain light. When he recognized Roddy he galloped to him, and with evident pleasure but without speaking, handed him the reins of the led pony. Then motioning to Roddy to wait, he rode rapidly down the road over which the American had just come. Roddy settled himself in the saddle, and with a smile of satisfaction beamed upon the ghostlike world around him. So far, at least, the adventure promised to be genuine. Certainly, he argued, Peter could not have prepared a joke so elaborate.
