“How did you learn who the murderer is?” inquired Frank.

“Quite accidentally, as I before remarked.”

“Didn’t Monte Murphy tell you?”

“No.”

“How then did you learn?”

“From the party himself.”

“Men who commit murder do not go around bragging about it.”

“The man is a close friend of mine,” said Bull.

“And you are quite willing to sacrifice him, eh?”

“He’d do the same on me,” growled the prisoner.
