"She fainted! Hum!" Prain looked so serious and perplexed that Gebb was impelled to question him further touching the matter.

"Why did she faint?" asked the detective, bluntly.

"I don't know--that is, I can't exactly say," stammered the other.

Gebb looked at the solicitor, who in his turn stared at the carpet, the ceiling, at the papers on his desk; anywhere but at his questioner.

"Mr. Prain," he said seriously, "you are not treating me fairly."

"I beg your pardon," said Prain, nervously--and as a rule he was not a nervous man, "I don't see how you make that out."

"I do!" replied Gebb, sharply. "You know the reason of that fainting."

"Perhaps I do; but I am not at liberty to reveal my knowledge. The secret is Miss Wedderburn's."

"Has it anything to do with this murder?"

"No," replied Prain, decisively. "That it has not."
