"Now, Ruth, be sensible," went on Alice, as she passed around back of her sister's chair. "You heard what was said. I'm sure those men have some designs on that patent Russ has worked so hard over. We must tell him about them, and put him on his guard."

"You may get into danger."

It was curious how, in this emergency—as she had often done of late—Alice took the lead over her older sister. And Ruth did not object to it, but seemed to follow naturally after Alice led the way.

"Danger!" laughed Alice softly, as she came to a position behind the screen, whence she could note who the men going out were. "There's no danger in a public restaurant like this. And I'm only going to make sure who that man is. Then we'll go tell Russ."

Ruth made no further objection, and turned to watch her sister. The men had come to a halt at the desk of the cashier, to pay their checks, and their backs were toward Alice. An instant later, however, one of them had turned around and faced toward the rear of the restaurant.

Alice darted behind the screen with a quick intaking of her breath. She had recognized the man, and was fearful lest he know her.

For he was the fellow with whom Russ had been in dispute in the hallway that day, when the DeVeres' door had flown open.

"Simp Wolley!" whispered Alice, in tense tones to Ruth. "It's that man who was after Russ's patent."

"Then don't let him see you."

"I won't—no danger. They're going out now. Come on!"
