were curtained and there was no sign of life. The broad piazza which ran around three sides of it was cluttered with dead leaves. [Illustration: _He lowered the rails, and Miss Arsdale led the way_] She took the key to the front door from her purse and he inserted it in the lock. "You wait out here," he commanded, "until I take a look around." "I would rather go in with you. I know the house." "I will open it up first," he said calmly, and stepping in before she had time to protest further, he closed the door behind him. He heard her clenched fists pounding excitedly on the panels.
