"No," the mason replied shortly.

"I thought maybe those Italians might have been sneaking about here. They're ugly fellows," Archie remarked.

"I didn't see nobody around."

"Some of those fellows are regular anarchists," Archie persisted. "They wouldn't stop at firing a house to get even with a man they're down on."

The mason stared at him out of his steely blue eyes, but said nothing. He began to understand what Archie was driving at, and a deep disgust for the man before him, who was trying to "put over" this cheap falsehood to "save his face," filled the mason's soul. The others had instinctively drawn away from them, and Clark himself looked as if he wanted to turn on his heel. But he listened.

"I shouldn't be surprised if the house had been set on fire," Archie continued confidentially. "I'm going to have detectives look into it. It must have been either that or spontaneous combustion in the drawing-room."

The mason's lips twitched ominously.

"But I think it was set on purpose!" Archie asserted.

"Oh, go to hell!" the mason groaned, his emotions getting the better of him. "Set, nothing!... Spontaneous combustion! You know how it got on fire better than anybody."

"What do you mean?" Archie demanded.
