"A woman," said Bill impressively. "Of course I thought it was going to be Robert-so did you, didn't you?-but it wasn't. It was a woman. Came quite late on Monday night in a car-driving herself-went off early next morning."

"Did he describe her?"

"Yes. She was middlin'. Middlin' tall, middlin' age, middlin' colour, and so on. Doesn't help much, does it? But still-a woman. Does that upset your theory?"

Antony shook his head.

"No, Bill, not at all," he said.

"You knew all the time? At least, you guessed?"

"Wait till to-morrow. I'll tell you everything to-morrow."

"To-morrow!" said Bill in great disappointment.

"Well, I'll tell you one thing to-night, if you'll promise not to ask any more questions. But you probably know it already."

"What is it?"

"Only that Mark Ablett did not kill his brother."

"And Cayley did?"

"That's another question, Bill. However, the answer is that Cayley didn't, either."

"Then who on earth-"

"Have some more beer," said Antony with a smile. And Bill had to be content with that.

They were early to bed that evening, for both of them were tired. Bill slept loudly and defiantly, but Antony lay awake, wondering. What was happening at the Red House now? Perhaps he would hear in the morning; perhaps he would get a letter. He went over the whole story again from the beginning-was there any possibility of a mistake? What would the police do? Would they ever find out? Ought he to have told them? Well, let them find out; it was their job. Surely he couldn't have made a mistake this time. No good wondering now; he would know definitely in the morning.

In the morning there was a letter for him.

CHAPTER XXI. Cayley's Apology

"My Dear Mr. Gillingham,

"I gather from your letter that you have made certain discoveries which you may feel it your duty to communicate to the police, and that in this case my arrest on a charge of murder would inevitably follow. Why, in these circ.u.mstances, you should give me such ample warning of your intentions I do not understand, unless it is that you are not wholly out of sympathy with me. But whether or not you sympathize, at any rate you will want to know-and I want you to know-the exact manner in which Ablett met his death and the reasons which made that death necessary. If the police have to be told anything, I would rather that they too knew the whole story. They, and even you, may call it murder, but by that time I shall be out of the way. Let them call it what they like.

"I must begin by taking you back to a summer day fifteen years ago, when I was a boy of thirteen and Mark a young man of twenty-five. His whole life was make-believe, and just now he was pretending to be a philanthropist. He sat in our little drawing-room, flicking his gloves against the back of his left hand, and my mother, good soul, thought what a n.o.ble young gentleman he was, and Philip and I, hastily washed and crammed into collars, stood in front of him, nudging each other and kicking the backs of our heels and cursing him in our hearts for having interrupted our game. He had decided to adopt one of us, kind Cousin Mark. Heaven knows why he chose me. Philip was eleven; two years longer to wait. Perhaps that was why.

"Well, Mark educated me. I went to a public school and to Cambridge, and I became his secretary. Well, much more than his secretary as your friend Beverley perhaps has told you: his land agent, his financial adviser, his courier, his-but this most of all-his audience. Mark could never live alone. There must always be somebody to listen to him. I think in his heart he hoped I should be his Boswell. He told me one day that he had made me his literary executor-poor devil. And he used to write me the absurdest long letters when I was away from him, letters which I read once and then tore up. The futility of the man!

"It was three years ago that Philip got into trouble. He had been hurried through a cheap grammar school and into a London office, and discovered there that there was not much fun to be got in this world on two pounds a week. I had a frantic letter from him one day, saying that he must have a hundred at once, or he would be ruined, and I went to Mark for the money. Only to borrow it, you understand; he gave me a good salary and I could have paid it back in three months. But no. He saw nothing for himself in it, I suppose; no applause, no admiration. Philip's grat.i.tude would be to me, not to him. I begged, I threatened, we argued; and while we were arguing, Philip was arrested. It killed my mother-he was always her favourite-but Mark, as usual, got his satisfaction out of it. He preened himself on his judgment of character in having chosen me and not Philip twelve years before!

"Later on I apologized to Mark for the reckless things I had said to him, and he played the part of a magnanimous gentleman with his accustomed skill, but, though outwardly we were as before to each other, from that day forward, though his vanity would never let him see it, I was his bitterest enemy. If that had been all, I wonder if I should have killed him? To live on terms of intimate friendship with a man whom you hate is dangerous work for your friend. Because of his belief in me as his admiring and grateful protege and his belief in himself as my benefactor, he was now utterly in my power. I could take my time and choose my opportunity. Perhaps I should not have killed him, but I had sworn to have my revenge-and there he was, poor vain fool, at my mercy. I was in no hurry.

"Two years later I had to reconsider my position, for my revenge was being taken out of my hands. Mark began to drink. Could I have stopped him? I don't think so, but to my immense surprise I found myself trying to. Instinct, perhaps, getting the better of reason; or did I reason it out and tell myself that, if he drank himself to death, I should lose my revenge? Upon my word, I cannot tell you; but, for whatever motive, I did genuinely want to stop it. Drinking is such a beastly thing, anyhow.

"I could not stop him, but I kept him within certain bounds, so that n.o.body but myself knew his secret. Yes, I kept him outwardly decent; and perhaps now I was becoming like the cannibal who keeps his victim in good condition for his own ends. I used to gloat over Mark, thinking how utterly he was mine to ruin as I pleased, financially, morally, whatever way would give me most satisfaction. I had but to take my hand away from him and he sank. But again I was in no hurry.

"Then he killed himself. That futile little drunkard, eaten up with his own selfishness and vanity, offered his beastliness to the truest and purest woman on this earth. You have seen her, Mr. Gillingham, but you never knew Mark Ablett. Even if he had not been a drunkard, there was no chance for her of happiness with him. I had known him for many years, but never once had I seen him moved by any generous emotion. To have lived with that shrivelled little soul would have been h.e.l.l for her; and a thousand times worse h.e.l.l when he began to drink.

"So he had to be killed. I was the only one left to protect her, for her mother was in league with Mark to bring about her ruin. I would have shot him openly for her sake, and with what gladness, but I had no mind to sacrifice myself needlessly. He was in my power; I could persuade him to almost anything by flattery; surely it would not be difficult to give his death the appearance of an accident.

"I need not take up your time by telling you of the many plans I made and rejected. For some days I inclined towards an unfortunate boating accident in the pond-Mark, a very indifferent swimmer, myself almost exhausted in a gallant attempt to hold him up. And then he himself gave me the idea, he and Miss Norris between them, and so put himself in my hands; without risk of discovery, I should have said, had you not discovered me.

"We were talking about ghosts. Mark had been even more vain, pompous and absurd than usual, and I could see that Miss Norris was irritated by it. After dinner she suggested dressing up as a ghost and frightening him. I thought it my duty to warn her that Mark took any joke against himself badly, but she was determined to do it. I gave way reluctantly. Reluctantly, also, I told her the secret of the pa.s.sage. (There is an underground pa.s.sage from the library to the bowling-green. You should exercise your ingenuity, Mr. Gillingham, in trying to discover it. Mark came upon it by accident a year ago. It was a G.o.dsend to him; he could drink there in greater secrecy. But he had to tell me about it. He wanted an audience, even for his vices.)

"I told Miss Norris, then, because it was necessary for my plan that Mark should be thoroughly frightened. Without the pa.s.sage she could never have got close enough to the bowling-green to alarm him properly, but as I arranged it with her she made the most effective appearance, and Mark was in just the state of rage and vindictiveness which I required. Miss Norris, you understand, is a professional actress. I need not say that to her I appeared to be animated by no other feeling than a boyish desire to bring off a good joke-a joke directed as much against the others as against Mark.

"He came to me that night, as I expected, still quivering with indignation. Miss Norris must never be asked to the house again; I was to make a special note of it; never again. It was outrageous. Had he not a reputation as a host to keep up, he would pack her off next morning. As it was, she could stay; hospitality demanded it; but never again would she come to the Red House-he was absolutely determined about that. I was to make a special note of it.

"I comforted him, I smoothed down his ruffled feathers. She had behaved very badly, but he was quite right; he must try not to show how much he disapproved of her. And of course she would never come again-that was obvious. And then suddenly I began to laugh. He looked up at me indignantly.

"'Is there a joke?" he said coldly.

"I laughed gently again.

"'I was just thinking,' I said, 'that it would be rather amusing if you-well, had your revenge."

"'My revenge? How do you mean?'

"'Well, paid her back in her own coin.'

"'Do you mean try and frighten her?'

"'No, no; but dressed up and pulled her leg a bit. Made her look a fool in front of the others.' I laughed to myself again. 'Serve her jolly well right.'

"He jumped up excitedly.

"'By Jove, Cay!' he cried. 'If I could! How? You must think of a way.

"I don't know if Beverley has told you about Mark's acting. He was an amateur of all the arts, and vain of his little talents, but as an actor he seemed to himself most wonderful. Certainly he had some ability for the stage, so long as he had the stage to himself and was playing to an admiring audience. As a professional actor in a small part he would have been hopeless; as an amateur playing the leading part, he deserved all that the local papers had ever said about him. And so the idea of giving us a private performance, directed against a professional actress who had made fun of him, appealed equally to his vanity and his desire for retaliation. If he, Mark Ablett, by his wonderful acting could make Ruth Norris look a fool in front of the others, could take her in, and then join in the laugh at her afterwards, he would indeed have had a worthy revenge!

"It strikes you as childish, Mr. Gillingham? Ah, you never knew Mark Ablett.

"'How, Cay, how?' he said eagerly.

"'Well, I haven't really thought it out,' I protested. 'It was just an idea.'

"He began to think it out for himself.

"'I might pretend to be a manager, come down to see her-but I suppose she knows them all. What about an interviewer?'
