"My dear young lady," said the detective. "I really can't give you an opinion at present. There are a score of points I must investigate, a dozen other people besides yourself whom I must question, before I can form any kind of conclusion. I hope that Sir David Southern may prove to be a much wronged man. But beyond that I can't go, just at present; and I shouldn't build too much on my help if I were you. I'm not infallible; far from it. And I certainly can't prove him innocent if he is guilty."
He stood up, shaking the sand out of his clothes.
"Let us go on, up to the castle," he said.
The gates were near at hand; in silence they breasted the steep incline of the drive, which wound and zigzagged up between high banks covered with rhododendron and bracken, and grown over with trees. After a quarter of a mile these gave place to an abrupt, grass covered slope, whose top had been smoothed and levelled by the hand of man, and from which on the far side rose the castle of Inverashiel, its stout and ancient framework disguised and masked by the modern addition to the building which faced the approach; a mass of gabled and turreted stonework in the worst style of nineteenth century architecture which in Scotland often took on a shape and semblance even more fantastically repulsive than it assumed in the south. The great tower that formed the principal remaining portion of the old building could just be discerned over the top of the flaring façade, but the nature of the site was such that most of the ancient fortress was invisible from that part of the grounds. Juliet stopped at the turn of the road.
"I will leave you here," she said, "you will not want me, I suppose? After you have finished, will you come to Lady Ruth Worsfold's house, and tell me what you think? It is just past the station turning; you will easily find your way, though the house is hidden by the trees. Your luggage will be there already, as Lady Ruth is going to put you up."
Mr. Mark McConachan, or rather Lord Ashiel, as he had now become, was in the act of ending a solitary meal, when Gimblet was announced. He went to meet the detective, forcing to his trouble-lined face a smile of welcome that lit up the large melancholy eyes with an expression few people could resist.
"I thought it was another of those newspaper fellows, but, thank goodness, I believe they're all gone now," he said. "I am exceedingly glad to see you, Mr. Gimblet. I should myself have asked you to come to our aid, but I found that Miss Byrne had been before me. I suppose you have seen her?"
