"But you know who have got them?"

"Yes, of course. It's all written down somewhere."

"Where?"

But Swayne "did not rightly know." He had the addresses in cipher somewhere, but he could not put his hand upon them. Half wild with fear, Colonel Tempest searched the pockets of the clothes that lay about the room, holding up their contents for Swayne to look at. It was like some hideous game of hide-and-seek. But the latter only shook his head.

"I have 'em somewhere," he repeated, "and there was a change not so long ago. When was it? May. There's one of 'em written down in cipher in my pocket-book in May, I know that."

"Here. This one?" said Colonel Tempest, holding out a greasy pocket-book.

"That's it," said Swayne. "Some time in May."

Colonel Tempest turned to the month, and actually found a page with a faint pencil scrawl in cipher across it.

"That's him," said Swayne. "James Larkin," and he read out a complicated address without difficulty.

"Will that find him?" asked Colonel Tempest, his hand shaking so much that he could hardly write down Swayne's words.
