Ward lost no time in engaging detectives to learn all they could of the cryptic bearded doctor; finding whence he had come and what Pawtuxet knew of him, and if possible discovering his current whereabouts. Supplying the men with one of the bungalow keys which Charles had yielded up, he urged them to explore Allen’s vacant room which had been identified when the patient’s belongings had been packed; obtaining what clues they could from any effects he might have left about. Mr. Ward talked with the detectives in his son’s old library, and they felt a marked relief when they left it at last; for there seemed to hover about the place a vague aura of evil. Perhaps it was what they had heard of the infamous old wizard whose picture had once stared from the paneled overmantel, and perhaps it was something different and irrelevant; but in any case they all half-sensed an intangible miasma which centered in that carven vestige of an older dwelling and which at times almost rose to the intensity of a material emanation.
