D uring the week that followed his employment, he saw nothing of Solino, though Ward met the old man for a few moments every day to receive his instructions. "It puzzles me," he confessed to Miles, "how the old chap lives. There's a private exit to the street from his rooms, but I could swear he never goes out. How could he in that wheelchair — no attendant. And yet he must. How would he get food?"
Justus Miles smiled lazily. "No mystery at all, Rusty. We're gone for hours at a time. What's to prevent him from phoning to have his meals brought in?"
"But I've questioned them at the restaurant and they say—"
"Good Lord! — is there only one restaurant in Manhattan?"
Yet Justus Miles himself could not help feeling there was something mysterious about Solino, but just how mysterious he did not realize — until, one evening, he stood with a half dozen of his fellow adventurers in a lonely spot on the Long Island coast and watched the darkness deepen around them. "We shall wait," said Solino presently, "until the moon comes up."
The moon rose at about nine o'clock, flooding the beach and the heaving expanse of water with a ghostly light. From the folds of Solino's cloak, close about his muffled throat, a peculiar ray of green light flashed out over the water. In answer, a green light flashed back, and presently, something low and black, like the body of a whale half submerged, stole towards the beach. Scarcely a ripple marked its progress, and the nose of it slid up on the sand. "Good Lord!" whispered Miles, grasping Ward by the arm: "it's a submarine!"
But the craft on which the surprised soldiers of fortune gazed was not an ordinary submarine. In the first place, there was no conning tower; and, in the second, from the blunt nose projected a narrow gangway bridging the few feet of water between the mysterious craft and the dry beach. But the men had little time to indulge in amazement. "Quick," said Solino; "load those boxes onto the gangway. No need to carry them further." He himself wheeled his chair into the interior of the submarine, calling back, "Hurry, hurry!"
T he adventurers accomplished the loading in a few minutes. "Now," came the voice of their employer, "stand on the gangway yourselves. Steady; don't move."
Under their feet they felt the gangway vibrate and withdraw from the land. For a moment they were in utter darkness; then a light flashed up and revealed a long, box-like room. The opening through which they had come had closed, leaving no sign of its existence.
In the center of the room stood a mechanism like a huge gyroscope, and a plunging piston, smooth and black, went up and down with frictionless ease. In front of what was evidently a control board sat a swarthy man with a large hairless head and peculiarly colored eyes. The adventurers stared in surprise, for this man, too, sat in a wheelchair, seemingly a cripple; but unlike Mr. Solino he wore no cloak, his body from the neck down being enclosed in a tubular metal container. The body must have been very small, and the legs amputated at the hips, since the container was not large and terminated on the seat of the peculiar wheel chair to which it seemed firmly attached.
