The sight that met their eyes when at last they entered the saloon was one that would have appalled hearts less stout and brave.

On the deck lay the skeleton of a man, with a rusty revolver not far off. There was a hole in the skull right behind, so that it was evident he had not died by his own hand.

On a half-rotten and slimy sofa lay another skeleton, and, horrible to relate, the shaft of a dagger or knife still protruded from the ribs on the left side. But the bony hand and arm that had held that knife lay by the side of mortal remains.

“A certain case of suicide,” said Antonio, and his voice sounded hollow and uncanny in this awful saloon.

Determined to elucidate the mystery if possible, Antonio, followed by Barclay, made his way to what seemed the chief state-room—no doubt the skipper’s.

As he walked across the deck towards it, small loathsome-looking brown crabs went scuttling across and hid in the darkest corners. Some were unwittingly crushed under foot, and the crunching noise added to the horror of the situation.

With the boathook Antonio dashed open the saloon door; then all three men retreated till the foul air escaped.

In doing so Barclay kicked a hassock or footstool. It fell in pieces, and all started back with a feeling of fear and dread, for out from the débris wriggled two snakes, or water-serpents, of a kind not uncommon on sandbanks in the Indian Ocean. The creatures made a dash for the companion-ladder, up which they threw themselves in a remarkable manner. The men in the boat alongside were startled to see the snakes leap from the scupper-holes of the derelict and dive into the sea.

Everything was rotten, slimy, and ghastly in this stateroom. There were curtains on the bed which gave way at a touch; the mattress and bedclothes fell to pieces when stirred with the boathook, clothes hung on the wall, but fell to the deck when Antonio entered.

But here in the corner was a safe. The door was shut but not locked, and as Barclay swung it open he found therein gold, watches, and a chronometer. These they took possession of. There was also a ship’s log, but all the first portions of it and its top cover were decayed and rotten.
