But though he spoke and acted thus boldly he fully recognised the seriousness of this new danger. Say that this man laid information against him at the first police station; say that it got to the knowledge of Detective Lambert who was searching everywhere for a clue to the mystery. What would be the consequence? A warrant would be immediately issued for his arrest, and a search warrant as well. The rope and grapnel, tied up in brown paper, was now under the bed of his room in Constable Pond's house, and the key of that room was in his pocket. How could he explain away his possession of the rope? He would be asked why he made no mention of it at the inquest; his silence regarding it would be a piece of damning evidence against him. And not the only piece. His prowling about in the neighbourhood of Catchpole Square at an early hour of the morning, as testified by Constable Applebee, was in the highest degree suspicious when taken in connection with his possession of the rope and grapnel. His knowledge of the habits of Samuel Boyd, gained during his employment as clerk in the house, would be against him. One thing was certain. He would be deprived of his liberty, and the contemplation of this contingency filled him with dismay. Everything depended upon his being free to carry out the plans he had formed, and therefore upon his turning the tables upon the old vagabond who sat leering into his face. And in the event of his being arrested, what would be said of him in Aunt Rob's home? Was it not probable, aye, more than probable, that they would suspect _him_ to be the murderer? He had woven a net for himself, and if he were not careful he would drag down Reginald with him. Press and public would say "collusion," and the chain of circumstantial evidence be too strong for him to break through. Admitting all this, he felt that any sign of weakness in the presence of Mr. Higgins would be fatal. There was nothing for it but to play the bold game. "I've a good mind," he said, slowly and sternly, "to go and give information against you." "What do you mean?" demanded Mr. Higgins, his features twitching more hideously than ever. Dick hailed these signs of discomposure with delight, and encouraged by the impression his sarcastic references to Mr. Higgins as an honest tradesman had produced he was quick to take advantage of it. He resembled the gambler who stakes his whole fortune upon the last throw.
