But what, French asked himself, had led to the whole dénouement? Was it not his, French’s, foresight and ingenuity at the inquest? He had devised and skilfully baited a trap for his victim, and lo! the victim had walked into it with the most commendable promptness. He had fallen for the dope, as French’s former acquaintance, Mrs. Chauncey S. Root of Pittsburgh, would have put it. And now a little energetic action and the man would pay the price of his folly. For some time after reaching his room French busied himself in putting in motion against the ingenious purchaser of rings the great machine of which he was a part. A telephone warning was sent to all stations that the man whose description had already been circulated in connection with the Starvel murders had disguised himself with a moustache and tinted glasses and had recently been in London occupied in certain business involving taxis and wedding rings. A number of men were put on to trace the taxi or taxis employed, others to try to obtain further information at the jewellers’, while still others were sent round the hotels in the hope of picking up a scent. It was not indeed until the late afternoon that French had time to settle down really to consider where he now stood. In the first place it was clear not only that Roper had remained in the country, but that he had kept himself in touch with events in Thirsby. Of course this latter did not mean much, for the circumstances of the Starvel case had created widespread interest and the details which came out at the inquest were fully reported in the papers. But Roper had evidently been uncertain as to how much the police knew, and French’s evidence had had the desired reassuring effect. It might, of course, have happened that Roper’s hand had been forced. He might have run out of cash to live on or he might have required a lump sum, say, to leave the country. But whatever the reason, he had determined on a coup. And very cleverly he had arranged it. He must have made over £18 a purchase, and if he bought forty rings in a day his profits would amount to over £700. £700 a day was not bad. The following day was Sunday, but by Monday evening reports had begun to come in from French’s little army of workers. Sixteen more shops had been found at which Roper had bought rings and changed £20 notes, and one of these notes bore a Starvel number. Moreover it had been established that his activities had extended over at least three days. Inquiries at the fashionable restaurants had revealed the fact that on the Tuesday a man answering Roper’s description had paid for his lunch at the Carlton with a similar note. French received these items thankfully, and having made a skeleton time-table of the three days in question, fitted each item into its appropriate place.
