When they had gone Captain Spade stood up, and his men rejoined him.

Had they not better profit by the chance thus unexpectedly afforded them to enter the room and secure Roch, who was in a semi-comatose condition, and then await Gaydon’s return, and seize the warder as he entered?

This would have involved considerable risk.  Gaydon, at a glance, would perceive that his patient was missing and raise an alarm; the doctor would come running back; the whole staff of Healthful House would turn out, and Spade would not have time to escape with his precious prisoner and lock the door in the wall after him.

He did not have much chance to deliberate about it, for the warder was heard returning along the gravel path.  Spade decided that the best thing to be done was to spring upon him as he passed and stifle his cries and overpower him before he could attempt to offer any resistance.  The carrying off of the mad inventor would be easy enough, inasmuch as he was unconscious, and could not raise a finger to help himself.

Gaydon came round a clump of bushes and approached the entrance to the pavilion.  As he raised his foot to mount the steps the four sailors sprang upon him, bore him backwards to the ground, and had gagged him, securely bound him hand and foot, and bandaged his eyes before he began to realize what had happened.

Two of the men then kept guard over him, while Captain Spade and the others entered the house.

As the captain had surmised, Thomas Roch had sunk into such a torpor that he could have heard nothing of what had been going on outside.  Reclining at full length, with his eyes closed, he might have been taken for a dead man but for his heavy breathing.  There was no need either to bind or gag him.  One man took him by the head and another by the feet and started off with him to the schooner.

Captain Spade was the last to quit the house after extinguishing the lamp and closing the door behind him.  In this way there was no reason to suppose that the inmates would be missed before morning.

Gaydon was carried off in the same way as Thomas Roch had been.  The two remaining sailors lifted him and bore him quietly but rapidly down the path to the door in the wall.  The park was pitch dark.  Not even a glimmer of the lights in the windows of Healthful House could be seen through the thick foliage.

Arrived at the wall, Spade, who had led the way, stepped aside to allow the sailors with their burdens to pass through, then followed and closed and locked the door.  He put the key in his pocket, intending to throw it into the Neuse as soon as they were safely on board the schooner.

There was no one on the road, nor on the bank of the river.

The party made for the boat, and found that Effrondat, the boatswain, had made all ready to receive them.

Thomas Roch and Gaydon were laid in the bottom of the boat, and the sailors again took their places at the oars.
