“It’s you, young master,” said Boulter. “Well, you’ve rowed my wherry time and again, and I don’t mind if you do, so long as you promise to tie her up when you get back.”

“Ah! You are kind. You are a friend,” said the foreigner. He produced a shilling, and was handing it to Martin when Boulter reached forward and took the coin.

“Thank’ee,” he said. “Young master will take ’ee quite safe, and I’ll get along to the Pig and Whistle.”

In another minute Martin was pulling the wherry out into mid-stream. The passenger sat in silence upon the stern thwart, still grasping his box.

There was now little traffic on the river. Here and there near the banks barges were moored, and the spars of larger vessels were outlined against the glooming sky. Glancing frequently over his shoulder Martin steered a course clear of obstructions, and in no long time came within sight of the Deptford shipyards.

Presently the passenger, who had not spoken a word, motioned Martin to land him at a jetty jutting out from a quay along the wall of a house overhanging the river. It had the appearance of an empty warehouse.

Martin was pulling round when the man changed his mind.

“No, not there,” he said. “Beyond; farther: at the stairs of Deptford.”

Martin sculled on, feeling that there was something mysterious about his passenger. He seemed anxious, or excited.

The wherry was almost opposite to the Deptford stairs when a cry broke from the passenger’s lips. Martin glanced round, and saw a boat approaching swiftly. It contained a single man, pulling hard against the tide.
