“What makes you think so?”

“There is a room up there that I’ve never seen anyone enter or leave. The door is always closed. Twice while passing the door I have heard strange sounds coming from that room.”

“This grows interesting,” admitted Frank. “Go on.”

“The first time,” said Bart, “I heard some one in there weeping and sobbing as if her heart would break.”

“Her heart?” came quickly from Merry’s lips.

“Yes.”

“Then it is a female?”

“Beyond a doubt. The second time I heard sounds in that room to-day after you rode away on the broncho. I heard some one singing in there.”

“Singing?”

“Yes. It was a love song. The voice was very sad and sweet, and still there seemed something of happiness in it.”
