"No," said Carrington, still very thoughtfully, "not impossible."
"Sir Reginald might never have seen it was a stranger till the man was fairly inside."
Carrington smiled and shook his head.
"Thin, Bisset; very thin. Why need the man have been a stranger at all?"
Bisset's face fell.
"But surely you're not believing yon story that it was Sir Malcolm and Miss Farmond after a'?"
His visitor stood absolutely silent for a full minute. Then he seemed suddenly to banish the line of thought he was following.
"Is it quite certain that those two are engaged?" he asked.
Bisset's face showed his surprise at the question.
"They all say so," said he.
