It was eight o'clock and the relief guard was coming from the after deck. The crowd of prisoners round the door held their breath to listen. “It's all planned,” says Gabbett, in a low growl. “W'en the door h'opens we rush, and we're in among the guard afore they know where they are. Drag 'em back into the prison, grab the h'arm-rack, and it's all over.”

“They're very quiet about it,” says the Crow suspiciously. “I hope it's all right.”

“Stand from the door, Miles,” says Pine's voice outside, in its usual calm accents.

The Crow was relieved. The tone was an ordinary one, and Miles was the soldier whom Sarah Purfoy had bribed not to fire. All had gone well.

The keys clashed and turned, and the bravest of the prudent party, who had been turning in his mind the notion of risking his life for a pardon, to be won by rushing forward at the right moment and alarming the guard, checked the cry that was in his throat as he saw the men round the door draw back a little for their rush, and caught a glimpse of the giant's bristling scalp and bared gums.

“NOW!” cries Jemmy Vetch, as the iron-plated oak swung back, and with the guttural snarl of a charging wild boar, Gabbett hurled himself out of the prison.

The red line of light which glowed for an instant through the doorway was blotted out by a mass of figures. All the prison surged forward, and before the eye could wink, five, ten, twenty, of the most desperate were outside. It was as though a sea, breaking against a stone wall, had found some breach through which to pour its waters. The contagion of battle spread. Caution was forgotten; and those at the back, seeing Jemmy Vetch raised upon the crest of that human billow which reared its black outline against an indistinct perspective of struggling figures, responded to his grin of encouragement by rushing furiously forward.

Suddenly a horrible roar like that of a trapped wild beast was heard. The rushing torrent choked in the doorway, and from out the lantern glow into which the giant had rushed, a flash broke, followed by a groan, as the perfidious sentry fell back shot through the breast. The mass in the doorway hung irresolute, and then by sheer weight of pressure from behind burst forward, and as it so burst, the heavy door crashed into its jambs, and the bolts were shot into their places.

All this took place by one of those simultaneous movements which are so rapid in execution, so tedious to describe in detail. At one instant the prison door had opened, at the next it had closed. The picture which had presented itself to the eyes of the convicts was as momentary as are those of the thaumatoscope. The period of time that had elapsed between the opening and the shutting of the door could have been marked by the musket shot.

The report of another shot, and then a noise of confused cries, mingled with the clashing of arms, informed the imprisoned men that the ship had been alarmed. How would it go with their friends on deck? Would they succeed in overcoming the guards, or would they be beaten back? They would soon know; and in the hot dusk, straining their eyes to see each other, they waited for the issue Suddenly the noises ceased, and a strange rumbling sound fell upon the ears of the listeners.
