The Vow by Paul Trent — Read

Baron De Croiseuil had half expected to hear from Gaunt, for he imagined that the papers which he had left with Sir Keith Hamilton might have caused that gentleman to communicate with the millionaire, with the idea of persuading him into silence. A couple of days passed and it was very evident that something must be done without delay, and the Baron reluctantly decided to cause an application to be made at Bow Street to secure a warrant for Gaunt's arrest. By this time numerous documents had arrived from Brussels, and among them were affidavits sufficiently strong to make out a prima facie case of murder. There were numberless ex-Congo officials in Belgium who would be prepared to swear to anything for a consideration, for their morals were warped, and their greed for gold insatiable.

So the Baron interviewed Mr. Simon Stone -- the notorious solicitor, who was engaged in every case where dirty work was required to be done skillfully, and gave him full instructions. But as he walked back to his hotel, de Croiseuil was not altogether satisfied with what he had done, for he knew that his case was a weak one, and that the arrest of John Gaunt would cause a great outcry. But it was not his wish to proceed to that extremity, and as he strolled along Piccadilly, he saw approaching a gentleman, at the sight of whom he uttered an exclamation of satisfaction.
