quickly, “What’s that? What’s that?” There was a noise of flying wings in the room before them, but not one of the boys was able to see any of the winged creatures. Back and forth they flew, the unseen birds, their wings noisily flapping and their cries steadily increasing in volume. Startled as all the boys were by the unexpected sound they withdrew to the porch in front of the door and in whispers talked over the best plan for them to follow. “I say we go ahead,” said Grant at last. “We don’t want to be scared out by a little thing like this.” “That’s all right,” agreed Fred. “You’re so bold, I’ll let you go ahead.

At the same time the sound of the flying creatures in the room was heard again and as if to make matters worse a sound very like a groan came from the stairway. The weird interruption was followed by a wild laugh that came from the same stairway and a moment later the confusion was increased by a sound
