“Yes,” said Harold, after a pause. “It was extremely odd. So odd that I know that you will pardon my attempting to explain it—at least just now. You will, I think, be satisfied if you have evidence that I was in London yesterday afternoon. I am anxious to go to my sister without delay. Surely some clue must be forthcoming as to the ruffian who did the deed.”

“The only clue—if it could be termed a clue—is the sheath of the dagger,” replied Major Wilson. “It is the sheath of an ordinary belt dagger, such as is commonly worn by the peasantry in Southern Italy and Sicily. Lord Fotheringay lived a good deal abroad. Do you happen to know if he became involved in any quarrel in Italy—if there was any reason to think that his life had been threatened?”

Harold shook his head.

“My poor father returned from abroad a couple of months ago, and joined Lady Innisfail’s party in Ireland. I have only seen him once in London since then. He must have been followed by some one who fancied that—that—”

“That he had been injured by your father?”

“That is what I fear. But my father never confided his suspicions—if he had any on this matter—to me.”

They had walked some little way up the road. They now returned slowly and silently.

A one-horse-fly appeared in the distance. When it came near, Harold recognized it as the one in which he had driven with Beatrice from the station to the hotel.

“If you will allow me,” said Harold to Major Wilson, “I will send to the hotel for my overcoat and hat.”

“Do so by all means,” said Major Wilson. “There is a decent little inn some distance on the road, where you will be able to get a brush down—you certainly need one. I’ll give my sergeant instructions to send some telegrams at the junction.”
