They had left the open land and were following a path through the bordering trees. Two abreast was uncomfortable, so Antony dropped behind, and further conversation was postponed until they were outside the boundary fence and in the high road. The road sloped gently down to the village of Waldheim a few red-roofed cottages, and the grey tower of a church showing above the green.

"Well, now," said Antony, as they stepped out more quickly, "what about Cayley?"

"How do you mean, what about him?"

"I want to see him. I can see Mark perfectly, thanks to you, Bill. You were wonderful. Now let's have Cayley's character. Cayley from within."

Bill laughed in pleased embarra.s.sment, and protested that he was not a blooming novelist.

"Besides," he added, "Mark's easy. Cayley's one of these heavy, quiet people, who might be thinking about anything. Mark gives himself away.... Ugly, black-jawed devil, isn't he?"

"Some women like that type of ugliness."

"Yes, that's true. Between ourselves, I think there's one here who does. Rather a pretty girl at Jallands" he waved his left hand "down that way."

"What's Jallands?"

"Well, I suppose it used to be a farm, belonging to a bloke called Jalland, but now it's a country cottage belonging to a widow called Norbury. Mark and Cayley used to go there a good deal together. Miss Norbury-the girl-has been here once or twice for tennis; seemed to prefer Cayley to the rest of us. But of course he hadn't much time for that sort of thing."

"What sort of thing?"

"Walking about with a pretty girl and asking her if she's been to any theatres lately. He nearly always had something to do."

"Mark kept him busy?"

"Yes. Mark never seemed quite happy unless he had Cayley doing something for him. He was quite lost and helpless without him. And, funnily enough, Cayley seemed lost without Mark."

"He was fond of him?"

"Yes, I should say so. In a protective kind of way. He'd sized Mark up, of course his vanity, his self-importance, his amateurishness and all the rest of it but he liked looking after him. And he knew how to manage him."

"Yes.... What sort of terms was he on with the guests-you and Miss Norris and all of them?"

"Just polite and rather silent, you know. Keeping himself to himself. We didn't see so very much of him, except at meals. We were here to enjoy ourselves, and well, he wasn't."

"He wasn't there when the ghost walked?"

"No. I heard Mark calling for him when he went back to the house. I expect Cayley stroked down his feathers a bit, and told him that girls will be girls....-Hallo, here we are."

They went into the inn, and while Bill made himself pleasant to the landlady, Antony went upstairs to his room. It appeared that he had not very much packing to do, after all. He returned his brushes to his bag, glanced round to see that nothing else had been taken out, and went down again to settle his bill. He had decided to keep on his room for a few days; partly to save the landlord and his wife the disappointment of losing a guest so suddenly, partly in case he found it undesirable later on to remain at the Red House. For he was taking himself seriously as a detective; indeed, he took himself seriously (while getting all the fun out of it which was possible) at every new profession he adopted; and he felt that there might come a time after the inquest, say when he could not decently remain at the Red House as a guest, a friend of Bill's, enjoying the hospitality of Mark or Cayley, whichever was to be regarded as his host, without forfeiting his independent att.i.tude towards the events of that afternoon. At present he was staying in the house merely as a necessary witness, and, since he was there, Cayley could not object to him using his eyes; but if, after the inquest, it appeared that there was still work for a pair of independent and very keen eyes to do, then he must investigate, either with his host's approval or from beneath the roof of some other host; the landlord of 'The George,' for instance, who had no feelings in the matter.

For of one thing Antony was certain. Cayley knew more than he professed to know. That is to say, he knew more than he wanted other people to know he knew. Antony was one of the "other people"; if, therefore, he was for trying to find out what it was that Cayley knew, he could hardly expect Cayley's approval of his labours. It would be 'The George,' then, for Antony after the inquest.

What was the truth? Not necessarily discreditable to Cayley, even though he were hiding something. All that could be said against him at the moment was that he had gone the longest way round to get into the locked office and that this did not fit in with what he had told the Inspector. But it did fit in with the theory that he had been an accessory after the event, and that he wanted (while appearing to be in a hurry) to give his cousin as much time as possible in which to escape. That might not be the true solution, but it was at least a workable one. The theory which he had suggested to the Inspector was not.

However, there would be a day or two before the inquest, in which Antony could consider all these matters from within The Red House. The car was at the door. He got in with Bill, the landlord put his bag on the front seat next to the chauffeur, and they drove back.

CHAPTER VIII. "Do You Follow Me, Watson?"

Anthony's bedroom looked over the park at the back of the house. The blinds were not yet drawn while he was changing his clothes for dinner, and at various stages of undress he would pause and gaze out of the window, sometimes smiling to himself, sometimes frowning, as he turned over in his mind all the strange things that he had seen that day. He was sitting on his bed, in shirt and trousers, absently smoothing down his thick black hair with his brushes, when Bill shouted an "Hallo!" through the door, and came in.

"I say, buck up, old boy, I'm hungry," he said.

Antony stopped smoothing himself and looked up at him thoughtfully.

"Where's Mark?" he said.

"Mark? You mean Cayley."

Antony corrected himself with a little laugh. "Yes, I mean Cayley. Is he down? I say, I shan't be a moment, Bill." He got up from the bed and went on briskly with his dressing. "Oh, by the way," said Bill, taking his place on the bed, "your idea about the keys is a wash-out."

"Why, how do you mean?"

"I went down just now and had a look at them. We were a.s.ses not to have thought of it when we came in. The library key is outside, but all the others are inside."

"Yes, I know."

"You devil, I suppose you did think of it, then?"

"I did, Bill," said Antony apologetically.

"Bother! I hoped you'd forgotten. Well, that knocks your theory on the head, doesn't it?"

"I never had a theory. I only said that if they were outside, it would probably mean that the office key was outside, and that in that case Cayley's theory was knocked on the head."

"Well, now, it isn't, and we don't know anything. Some were outside and some inside, and there you are. It makes it much less exciting. When you were talking about it on the lawn, I really got quite keen on the idea of the key being outside and Mark taking it in with him."

"It's going to be exciting enough," said Antony mildly, as he transferred his pipe and tobacco into the pocket of his black coat. "Well, let's come down; I'm ready now."

Cayley was waiting for them in the hall. He made some polite inquiry as to the guest's comfort, and the three of them fell into a casual conversation about houses in general and The Red House in particular.

"You were quite right about the keys," said Bill, during a pause. He was less able than the other two, perhaps because he was younger than they, to keep away from the subject which was uppermost in the minds of them all.

"Keys?" said Cayley blankly.

"We were wondering whether they were outside or inside."

"Oh! oh, yes!" He looked slowly round the hall, at the different doors, and then smiled in a friendly way at Antony. "We both seem to have been right, Mr. Gillingham. So we don't get much farther."

"No." He gave a shrug. "I just wondered, you know. I thought it was worth mentioning."

"Oh, quite. Not that you would have convinced me, you know. Just as Elsie's evidence doesn't convince me."

"Elsie?" said Bill excitedly. Antony looked inquiringly at him, wondering who Elsie was.
