“When was that?”

“A day or two later. He called here to introduce Mr. Garside, whom he recommended very highly, and whom I had consented to employ on trial.”

“Just so,” Nick remarked. “I infer that Mr. Garside has proved satisfactory.”

“Yes. His position is not a difficult one, as far as that goes, and he has filled it capably. I rather like him, moreover, for he appears to be very much of a gentleman.”

“Did he have other recommendations except that of Dunbar, your former secretary?”

“No, he did not, nor did I require any.”

“As a matter of fact, then, all that you really know about Garside is what Dunbar told you,” Nick observed.

Clayton eyed him more sharply. Not only the remark, but also the detective’s voice, were tinged with a subtle, sinister significance that could not be overlooked.

“What do you mean, Nick?” he demanded. “What do you imply by that?”

“Oh, nothing of consequence, perhaps,” Nick now said carelessly.
