"The house has been broken into?"

"Yes."

"The man who broke into it did the deed," said Reginald, in a low, musing tone; then, after a pause, "But the blood--the blood! How to account for that? How did you get into the house?"

"Through the front door."

"But--the key!" exclaimed Reginald, and Dick fancied he detected signs of confusion. "Where did you get the key from?"

"A policeman scaled the wall at the back of the house, and entered through the broken window. He found the key in your father's room, and he came down and let us in."

"He had to draw the bolts?"

"The door was not bolted, and the chain was not up."

"Then my father couldn't----," said Reginald, and suddenly checked himself. "Go on."
