“The servants are kind of scared,” said Chick. “But I think that is only because they know Mr. Anderton is lying dead in his bedroom. Only Ruggins and one of the maids know he was killed, and they are keeping their mouths shut.”

“I hope they are,” remarked Nick coldly.

“You can depend on that. Ruggins is a close-mouthed fellow, and he has the girl hypnotized, I think. She has an idea he is the greatest ever, and he can make her do anything. I heard some of the other maids talking about Ruggins and Amelia going to be married next spring.”

Nick Carter smiled at this story of romance, which he regarded as a lucky thing, if it would have the effect of keeping the maid from talking. But he made no comment. He only asked Chick how he had found out about the house next door.

“Ruggins told me,” replied Chick. “Oh, yes. And he said something else. There is a tall Japanese professor, who used to visit there sometimes.”

“How do you know he was Japanese?” interrupted Nick.

“Ruggins. He said so. I told him Japanese men were not generally tall. He came back at me by saying this one was, so there was nothing more to be said. The professor’s name is Tolo. That’s all Ruggins could tell me—Professor Tolo.”

There came a knock at the door at that moment, and Chick, at Nick Carter’s request, opened it. He confronted Ruggins, who had come up with a card in his hand.

“Gentleman would like to speak to Mr. Carter,” he announced.

Nick looked at the name on the card. Then he started, as he told Ruggins to send the gentleman up.
