When he finally recovered the use of his faculties it was to discover himself the possessor of a violent headache. The pain came in such fearsome throbs that it was well nigh unendurable. The lamp still sputtered dimly where the professor had left it. At the moment it was on the point of going out altogether. The reporter noticed this, and over him stole a sense of panic. What if the light should fail altogether, leaving him lying in the dark in this frightful place! Still dizzy and sick, he managed to rise upon his elbows enough to complete a survey of the room. He was still in the laboratory of Professor Kell, but that worthy had disappeared. Of Handlon there was no sign. The mysterious apparatus, of which he now had but a vague remembrance, also had vanished. His thoughts became confused again, and wearily he passed a hand over his brow in the effort to collect all of his faculties. The lamp began to sputter, arousing him to action. Desperately he fought against the benumbing sensation that was even again stealing over him. Gradually he gained the ascendancy. He struggled dizzily to his feet and took a few tentative steps. Where was Handlon? He decided his friend had probably recovered from the drug first and was gone, possibly to get a doctor for him, Perry. However, he must make some search to determine if Skip had really left the premises. As he walked through the open door the lamp in his hand gave a last despairing flicker and went out. From there he was forced to grope his way down the dark hall to the stairs. Just how he reached the lower floor he was never able to remember, for as yet all the effect of the powerful drug had not worn off. He had a dim recollection of being thankful to the ancestor of Kell who had provided such thick carpets in these halls. Thanks to them his footsteps had been noiseless, at any rate. What was Kell's real object in giving them those drugged cigars? he wondered. How long had they been under the influence of the lethal stuff? Surely several hours. Upon glancing through a hall window he found that outside was the blackness of midnight. * * * * * Cautiously he explored the desolate chambers on the ground floor: the kitchen--where it could be plainly seen that cooking of a sort had been done--the barn, and woodshed. Not a living thing could he find, not even the huge wolf-hound which had attacked them in so strange a manner that afternoon. By now he was quite frankly worried on Handlon's account. At that moment, could he have known the actual fate that had overtaken his companion, it is quite probable he would have gone mad. He stumbled back and into the dark front hall, shouting his friend's name. The response was a hollow echo, and once or twice he thought he heard the ghost of a mocking chuckle.
