Harold looked alarmed.

"I wouldn't bother with a detective," he said. "They don't know half as much as they pretend."

"I am inclined to agree with Harold," said Mrs. Merton. "I will act as my own detective."

Save for the compliment to Harold, Mrs. Tracy was not pleased with this speech of her aunt.

"At any rate," she said, "you would do well to keep a strict watch over that boy, Luke Walton."

"I shall," answered the old lady, simply.

Mrs. Tracy looked triumphant.

Warner kept silent, but a transient smile passed over his face as he saw how neatly Aunt Eliza had deceived his astute sister.

"What do you think, Warner?" asked Mrs. Tracy, desirous of additional support.

"I think Aunt Eliza will get at the truth sooner or later. Of course I will do anything to help her, but I don't want to interfere."
