"Our man is no foreigner," I said. "Did they give themselves a name?"

"The landlord asked the one who stayed behind for his name," replied Lucilla. "He said it was 'Dubourg.'"

This confirmed me in my belief that I had guessed right. "Dubourg" is as common a name in my country as "Jones" or "Thompson" is in England—just the sort of feigned name that a man in difficulties would give among us. Was he a criminal countryman of mine? No! There had been nothing foreign in his accent when he spoke. Pure English—there could be no doubt of that. And yet he had given a French name. Had he deliberately insulted my nation? Yes! Not content with being stained by innumerable crimes, he had added to the list of his atrocities—he had insulted my nation!

"Well?" I resumed. "We have left this undetected ruffian deserted in the public-house. Is he there still?"

"Bless your heart!" cried the old nurse, "he is settled in the neighborhood. He has taken Browndown."

I turned to Lucilla. "Browndown belongs to Somebody," I said hazarding another guess. "Did Somebody let it without a reference?"

"Browndown belongs to a gentleman at Brighton," answered Lucilla. "And the gentleman was referred to a well-known name in London—one of the great City merchants. Here is the most provoking part of the whole mystery. The merchant said, 'I have known Mr. Dubourg from his childhood. He has reasons for wishing to live in the strictest retirement. I answer for his being an honorable man, to whom you can safely let your house. More than this I am not authorized to tell you.' My father knows the landlord of Browndown; and that is what the reference said to him, word for word. Isn't it provoking? The house was let for six months certain, the next day. It is wretchedly furnished. Mr. Dubourg has had several things that he wanted sent from Brighton. Besides the furniture, a packing-case from London arrived at the house to-day. It was so strongly nailed up that the carpenter had to be sent for to open it. He reports that the case was full of thin plates of gold and silver; and it was accompanied by a box of extraordinary tools, the use of which was a mystery to the carpenter himself. Mr. Dubourg locked up these things in a room at the back of the house, and put the key in his pocket. He seemed to be pleased—he whistled a tune, and said, 'Now we shall do!' The landlady at the Cross-Hands is our authority for this. She does what little cooking he requires; and her daughter makes his bed, and so on. They go to him in the morning, and return to the inn in the evening. He has no servant with him. He is all by himself at night. Isn't it interesting? A mystery in real life. It baffles everybody."

"You must be very strange people, my dear," I said, "to make a mystery of such a plain case as this."

"Plain?" repeated Lucilla, in amazement.

"Certainly! The gold and silver plates, and the strange tools, and the living in retirement, and the sending the servants away at night—all point to the same conclusion. My guess is the right one. The man is an escaped criminal; and his form of crime is coining false money. He has been discovered at Exeter—he has escaped the officers of justice—and he is now going to begin again here. You can do as you please. If I happen to want change, I won't get it in this neighborhood."
