"I'll take the earliest opportunity of seeing Lamb and Drummond," Jack resolved. "The affair will interest them, and it may lead to something. But I shan't bother about it—I didn't value the picture very highly, and the thief almost deserves to keep it for his cleverness."

During the next three days, however, Jack was too busy to carry out his plan—at least in the mornings. Not for any consideration would he have sacrificed his afternoons, for then he met Madge in Regent's Park, and spent an hour or more with her, reckless of extortionate cab fares from Ravenscourt Park to the neighborhood of Portland Terrace. On the second night, dining in town, he met Victor Nevill, and had a long chat with him, the two going to a music-hall afterward. Jack was discreetly silent about his love affair, nor did he or Nevill refer to the little incident near Richmond Hill.

At the end of the week Jack's opportunity came. He had finished some work on which he had been employed for several days, and soon after breakfast, putting on a frock coat and a top hat he went off to town. He presented a card at Lamb and Drummond's, and the senior partner of the firm, who knew him well by reputation, invited him into his private office. On learning his visitor's errand, Mr. Lamb evinced a keen interest in the subject. He listened attentively to the story, and asked various questions.

"Here is the letter from my friend in Paris," Jack concluded. "You will understand its import. It shows conclusively that M. Marchand came to my studio under a false name, and leaves no room for doubt that it was he who stole my duplicate Rembrandt."

"I agree with you, Mr. Vernon. It is a puzzling affair, and I confess I don't know what to make of it. But it is exceedingly interesting, and I am very glad that you have confided in me. I think it will be best if we keep our knowledge strictly to ourselves for the present."

"By all means."

"I except the detectives who are working on the case."

"Yes, of course. They are the proper persons to utilize the information," assented Jack. "It should not be made public."

"I never knew that a copy of Von Whele's picture was in existence," said Mr. Lamb. "I need hardly ask if it is a faithful one."

"I am afraid it is," Jack replied, smiling. "I worked slowly and carefully, and though I was a bit of an amateur in those days, I was more than satisfied with the result. The pictures were of the same size; and I really don't think many persons could have distinguished the one from the other."
