Indeed, it was true. Walter bent to the table to hide a blush. His letter dealt, in suspicious detail, with the charms and graces of Nellie Roe.

At last the missive was addressed and sealed. It was nearly ten o’clock, and London was quieting down for the night, when the two quitted their cabin and walked to the larger saloon where Sir Thomas Roe, with Captain Davis, the commander of the Defiance, was busy with many documents.

They talked there a little while. Suddenly they heard the watch hailed by a boat alongside.

“What ship is that?”

“Who hails?”

“The King’s officer.”

Roe sprang to his feet and rushed out, for the cabin was in the poop, and the door was level with the main deck. The others followed. In the river, separated from the vessel by a few feet of mud, was an eight-oared barge filled with soldiers.

“’Fore God!” he whispered to Mowbray, “they have found your retreat.”

They turned towards the wharf. A company of halberdiers and arquebusiers had surrounded it and already an officer was advancing towards the gangway.

“Bid Sainton offer no resistance,” said Roe, instantly. “At best, you can demand fair hearing, and I will try what a bold front can do. Remember, you are sworn volunteers for my mission to Guiana.”
