"He has threatened all sorts of things. Look out for him, Mr. Hatch. So he dined with Mr. Scott, did he? And Mr. Scott was taken ill at the Waldorf! Mr. Hatch, when I leave here I shall call on Mr. Scott's physician and have a talk with him. My suspicions are thoroughly aroused."

"You don't suspect foul play, do you?"

"As I have said, my suspicions are thoroughly aroused. This whole affair is queer."

At this moment the chauffeur uttered an exclamation of satisfaction, backed from beneath the machine, wrench in hand, and announced that the breakdown was remedied at last.

Frank remained until the machine was ready to start and Warren Hatch had stepped into it. Mr. Hatch waved his hand and was soon lost to view down the splendid park road.

Just as Merry was on the verge of entering the restaurant, Inza, pale and agitated, came hurrying to him.

"That man is here!" she said, her voice shaking. "I don't know why he frightens me so. I was seated inside, glancing at a magazine, when I happened to look up, and there he stood not more than five feet away. I had not heard a sound, but he was there, and those eyes were fastened on me in a manner that made my blood turn cold. I gave a cry and sprang up. Then he spoke, and, if possible, his voice terrified me even more than his eyes, for it was the voice of your bitterest enemy, Porfias del Norte. Of course, I know Del Norte is dead, Frank; but this man alarms me all the more because of that."

"What did he say to you?"

"He begged my pardon and said he had not meant to alarm me. He was very courteous, just the same as Del Norte. Can he be a relative of your enemy?"

"I don't think so, Inza. Where is he now?"
