With more boldness than the occasion perhaps really justified he descended the stairs and proceeded to examine the ground floor rooms minutely. The first was the room through which he had made entrance to the house. It proved to be but a storeroom containing nothing of interest, and he soon decided to waste no more time on it. The adjoining chamber, however, yielded some surprising finds. He had pushed back a dusty portiere to find himself in what could be nothing less than the Professor's sleeping chamber. At present the bed was unoccupied, though it showed signs of recent use. The electric torch played swiftly over every possible corner which could constitute a hiding place for an assassin, revealing nothing. Now the ever-searching ray fell upon an old-fashioned dresser, on which was piled a miscellaneous array of articles. Here were combs, brushes, a wig, a huge magnifying glass, and a gold watch. With a barely suppressed exclamation, Jimmie pounced upon the gold timepiece. Handlon's! So well did he know the particular design of his watch that he could have recognized it in the dark by sense of touch alone. So the old man was not averse to robbery among his other activities! The former two-story man thought fast. Handlon had probably been done in, and the body had been disposed of in some weird manner. The only thing that remained to be done, since the unlucky photographer was evidently past human help, was to cut short the Professor's list of murders. * * * * * With the intention of missing no essential detail O'Hara swept the ray of the searchlight around the chamber once more, but discovered no more of importance. Deciding that the sleeping chamber could yield no further clue he shut off the tell-tale ray and stepped noiselessly back into the next room. Here he groped his way around until he encountered a door, which stood open. A moment's cautious exploration with an outstretched foot revealed the top step of a descending staircase. No faintest glimmer of light was visible, but muffled sounds proceeding from the depths told him that someone was below. With infinite care, feeling his way gingerly over the rickety old steps and fearful that an unexpected creak from one of the ancient boards would at any moment prove his undoing, he commenced the descent. Once a board did groan softly, causing him to stop in his tracks and stand with bated breath. He listened for sign of a movement below, while his heart loudly told off a dozen strokes. Stealthily he continued his progress, until finally soft earth under his feet told him he had reached the cellar bottom.
