When the two Lascars had come aboard, and beheld the condition of the Mangalore, they loudly refused to remain. She would go to pieces with the first gale—yes, but not with them as her crew; and in spite of every denunciation and expostulation that the captain of the launch could devise—backed up by Truman, with broken Arabic and forcible gestures—the two cowards deserted the ship, and returned to Suakim.

Previous to taking over charge, Jack Truman had gleaned some particulars of the wreck. She had gone aground most unexpectedly, when the passengers were all at lunch; there was no panic, everything had been managed with the utmost pluck and coolness. The weather was calm, and passengers had gone off comfortably in boats, had landed about four o’clock in the afternoon, and been subsequently transported on to Suakim. The level-headed captain carried away his log-book, chronometer, and most of his possessions in the steam-launch, and had been warmly applauded for his courage, and resource.

Jack accepted the desertion of the Lascars with surprising sangfroid; he was accustomed to being alone. This, however, was a new kind of solitude—a solitude at sea. He scrambled about the deck, and explored the abandoned steamer from end to end. There was the long saloon, the smashed crockery, the passengers’ cabins, with their clothes and belongings scattered about, precisely as they had abandoned them. He discovered quantities of stores, and quantities of rats, and as the result of a careful inspection, he decided to take up his quarters in the captain’s cabin. Here, he made up a bed, and after a light supper, turned in.

In a day or two the caretaker became accustomed to his novel position; he smoked a good deal, he read novels—the property of the late passengers—he sat and stared for hours at the sea, or jagged coast-line, and some distant rocky islands, but he never once saw smoke or sail. His sole companion was the ship’s cat, a bony, lean, uncanny looking animal, with the pointed face peculiar to the Eastern feline. Sometimes at night, listening to the wash of the waves, it had seemed to Jack that the grey Grimalkin was not his sole ship-mate, unless his imagination was playing tricks. He seemed to hear a footstep, a heavy and yet a stealthy footstep. The experience was distinctly unpleasant, as he knew perfectly well that there was not a human being but himself within many miles. Jack did not believe in ghosts, and yet when alone, as he was, even a strong man may succumb to superstition. Solitude and silence evoke strange thoughts. He had overhauled the entire ship, and even examined the cargo; to his surprise, it proved to consist of boxes full of scrap-iron; this at once raised his suspicions—scrap-iron, at eighteen shillings a ton, was not worth its carriage all the way to Singapore! Then he made another strange discovery—he was wonderfully agile in getting about, even when he had to crawl and creep; down in the hold were three great holes in the ship’s side, caused by dynamite exploded from within! This was astounding. Did it mean that the captain had deliberately scuttled the Mangalore? Now if he could but find a scrap of writing as clue, or a witness! If he could but prove that the steamer had been purposely cast away, his future was made! He would inform the underwriters, save them an enormous loss, and possibly secure a generous reward—say £10,000.

With such an incentive, Jack worked ceaselessly. He searched almost day and night, anxious to discover some clue before he was relieved, or the derelict went to pieces, and he was compelled to abandon her, and take to the boat. He believed he might find the desired object in the captain’s cabin, and every day he examined it. Every day he turned out the bunk, the drawers, the desk; he lifted the carpet—but all proved useless.

The cat and the caretaker had become close friends; she accorded him her society; twice a day he gave her some tinned milk in a saucer (for himself, he lived on the stores), and she in return showed her gratitude by occasionally bringing him a dead rat. The ship was alive with them; what they existed on was a mystery; but they overran the saloon, the lower deck, and swarmed up the rigging. Truman often shot them with his revolver—practice, to keep his eye in!

One hot, airless afternoon he was lying in his bunk trying to sleep, when suddenly he was disturbed by an extraordinary commotion behind the wainscot; a violent scuffling and scratching. The enterprising cat had evidently got in there, and could not find her way out. He had missed her, the whole day. So that was where she was! He called, and she began to mew piteously and continuously. Well, there was nothing for it but to break in the panel, which he proceeded to do, with a series of violent kicks. Presently, as a result, the cat crawled forth, looking extremely dusty and dejected, and as she emerged from the woodwork, a little ball of white paper rolled out after her. Jack Truman stooped and picked it up and examined it curiously. Was it a find? It was! He discovered a creased plan of the ship, on which were three crosses in red ink, indicating the exact spot at which the dynamite was placed, and there was also a scrap of a letter evidently addressed to the captain.

“Off coast. Lat. ... can’t miss it ... tower rock ... it daytime ... wire as arrang....”

So there was his fortune at last, thanks to the cat! he had found the clue, and the whole thread was complete! For some time he sat on the side of his bunk, with the paper still in his hand, revelling in an ecstasy of exaltation. The two morsels of dusty paper might bring him Nancy. What should he set about first? He must be cool, and collected, and not act hastily. It was full moon, and the sea was smooth as oil; after sundown he would get the boat, row ashore, and walk during the night to a little station thirty miles up the coast, and from there despatch a runner, or a camel man, to Suakim. Meanwhile he would be compelled to leave the cat in temporary charge of the Mangalore!

Talking of full moon, what was this enormous shadow on the sky-light? He looked up, and was confronted by a pair of watery grey eyes, and a large crimson face. In another moment the face was thrust into the cabin and a tall bare-footed man in blue shirt and trousers said hoarsely:
