The morning of April sixth dawned clear, and both explorers were at the bungalow by ten o'clock. Mr. Ward had the key, and an entry and cursory survey were made. From the disordered condition of Dr. Allen's room it was obvious that the detectives had been there before, and the later searchers hoped that they had found some clue which might prove of value. Of course the main business lay in the cellar; so thither they descended without much delay, again making the circuit which each had vainly made before in the presence of the mad young owner. For a time everything seemed baffling, each inch of the earthen floor and stone walls having so solid and innocuous an aspect that the thought of a yawning aperture was scarcely to be entertained. Willett reflected that since the original cellar was dug without knowledge of any catacombs beneath, the beginning of the passage would represent the strictly modern delving of young Ward and his associates, where they had probed for the ancient vaults whose rumour could have reached them by no wholesome means.
