“Shouldn’t we turn back?” Rosanna whispered nervously.

“Let’s wait until he begins to play the organ.”

They listened expectantly. Minutes passed but not a strain of music did they hear.

“That’s queer,” Penny murmured. “I’m sure Caleb is the one who has been disturbing the household with his ghost music. Why doesn’t he play as he’s always done before?”

They both knew that the wall was not soundproof. For that matter they could hear old Caleb walking about in the room.

“He must be up to new tricks tonight,” Penny whispered.

“He’ll be coming back here any minute. Let’s get away before he catches us.”

Penny was reluctant to leave, for it struck her that Caleb Eckert had come to the Winters’ house for a different purpose than that of his usual nightly visit. She was curious to learn what it was.

“Listen!” she warned, as they heard a strange noise from within.

“It sounded like a door closing,” Rosanna declared.
