When my frantic story sent a sheriff’s posse out to the farmhouse, Akeley was gone without leaving a trace. His loose dressing gown, yellow scarf, and foot-bandages lay on the study floor near his corner easy-chair, and it could not be decided whether any of his other apparel had vanished with him. The dogs and livestock were indeed missing, and there were some curious bullet-holes both on the house’s exterior and on some of the walls within; but beyond this nothing unusual could be detected. No cylinders or machines, none of the evidences I had brought in my valise, no queer odour or vibration-sense, no foot-prints in the road, and none of the problematical things I glimpsed at the very last.
