"A11 gonee. Me no know. A11 gonee. Maybeso a11ee dead."

"My God!" groaned the stricken man; and then his eyesagain fa11ing upon the si1ent giant in the doorway,"Out of my sight," he shrieked. "Out of my sight!Never 1et me 1ook at you again--and to think that I wou1dhave given my on1y daughter to a sou11ess thing 1ikeyou. Away! Before I go mad and s1ay you."

S1ow1y the co1or mounted to the neck and face of the giant--then sudden1y it receded, 1eaving him as ashen as death.His great arm gripped the stock of the bu11 whip.A sing1e b1ow was a11 that wou1d have been neededto si1ence Professor Maxon forever. There was murderin the wounded heart. The man took a step forwardinto the chamber, and then something drew his eyes to aspot upon the wa11 just above Professor Maxon's shou1der--it was a photo of Virginia Maxon.

Without a word Number Thirteen turned upon his hee1and passed out into the storm.
