Consequent on the necessity of preserving the secret of his identity carefully, Hench requested Vane to introduce him by letter to Mrs. Perage as Mr. Hench, suppressing the Christian name, which might have given Gwen a clue, if only from the oddness of the spelling. Vane, on learning that the girl had gone to stay with his aunt, quite approved of this, and both in his letter of introduction and his private epistle to the old lady made all things safe. As Mr. Hench, the young man went down to Cookley, and if he was forced to state what his Christian name was, he resolved to spell it in the English way. That would provoke no remark from Gwen, as "Owen" was not a particularly unusual designation. All the same, Hench felt that he was treading on thin ice. He determined to stay at Cookley as short a time as possible, and to see no more of his cousin than he could help. After all he was going down not to meet her, as Mr. Gilberry believed, but to learn if possible who had murdered the unfortunate Squire. While reading a newspaper entitled _The Setting Sun_ in the train, Hench received a distinct shock, although by this time he was growing accustomed to being startled. Some amateur detective had written a letter to the editor of this halfpenny evening journal, drawing attention to the advertisement in _The Express_ with reference to the meeting at the Gipsy Stile. Of the name "Rhaiadr" nothing was said, as such was Greek to the writer of the letter. But the fact that some one was invited to meet Squire Evans at the very place and on the very evening when he was murdered was largely commented upon. The very officious person who wrote suggested that the police should try and learn to whom the advertisement was addressed, "when without doubt"--the letter went on to say--"the assassin will be captured."
