"Carson!" he gasped, falling back.

"What's the matter with you?" demanded Hardwick.

"Dat's der chap wot followed Ferris ter my house."

"Followed Ferris. When?"

"Der night he brung me dat letter from you about dat bus'ness over to der—you know."

"You are sure?"

"Sure," repeated Macklin, in deep disgust. "I t'ink I am."

"How did you happen to catch him?"

"He was spyin' at der door, same as here. We collared him, and knocked him down. I t'ought he was dead, an' me an' Ferris chucked him in a vat in der cellar of der old pickle factory."

"Ferris said nothing of this to me," said Hardwick.
