"Then there is a secret?" insisted Mallow.

Mr. Brock shifted uneasily. "Whose life is free from sin?" he said, in low tones. "Yes, there--is--a secret."

"Had it to do with Olive's marriage?"

"Yes; if she had refused Angus, there might have been trouble."

"What kind of trouble?"

"Don't ask me," said the vicar, with a shiver.

"I must ask you. Olive guesses that there is a secret, and she wishes to know it."

"She shall never know it from me," said the vicar, his face more pallid than ever. "I say let the dead past bury its dead."

"You said that before when you read that letter. The secret is told in that enclosed document?"

"Yes," said Brock, reluctantly.
