Slocum’s hand emerged from his scarlet silk sleeve and moved a black knight. “There.”

“Jolly good,” Marvell said. “Oh, jolly good.”

Slocum withdrew his dreaming gaze from the board and turned it on me. “Yes?”

“You said you would see Mr. Archer?” the housekeeper faltered.

“Mr. Archer? Oh. Yes. Come in, Mr. Archer.” Slocum’s voice was weak and vaguely peevish.

Mrs. Slocum left the room. I stood where I was. Slocum and Marvell projected an atmosphere, a circle of intimacy, which I didn’t care to enter. Nor did they want me to enter it. Their heads were turned toward me at the same impatient angle, willing me to be gone. To leave them to the complex chess-play between them.

“I hope that you’re recovering, Mr. Slocum.” I had nothing better to say.

“I don’t know, I have had a perfectly dreadful series of shocks.” Self-pity squeaked behind the words like a rat behind the wall. “I have lost my mother, I have lost my wife, my own daughter has turned against me now.”

“I’m standing by, dear fellow,” Marvell said. “You can count on me, you know.” Slocum smiled weakly. His hand moved toward Marvell’s, which was resting slack by the chessboard, but paused short of it.

“If you’ve come about the play,” Marvell said to me, “I’m afraid I have to confess we’ve given it up. After all that’s happened, it may be months or years before I can regain the world of imagination. Poor dear James may never act again.”

“No great loss to the theatre,” Slocum said with quiet pathos. “But Mr. Archer isn’t interested in the play, Francis. I’d supposed you knew by now that he’s a detective. I imagine that he’s looking for his pay.”

“I have been paid.”

“That’s just as well. You’d never have a penny out of me. May I hazard a guess as to who paid you?”

“You needn’t. It was your wife.”

“Of course it was! And shall I tell you why?” He leaned forward, clutching the bedclothes. His eyes were bright with fever or passion. The silver face was peaked and hollowed like an old man’s. “Because you helped her to murder my mother, didn’t you? Didn’t you?”

Marvell uncoiled his legs and stood up, his face averted in embarrassment.

“No, Francis, please don’t go. I want you to hear this. I want you to know the sort of woman I’ve had to spend my life with.”

Marvell slumped back into the chair and began to bite his knuckles.

“Go on,” I said. “This is interesting.”

“It came to me the night before last. I lay here thinking the night through, and I saw the whole thing plainly. She’d always hated my mother, she wanted her money, she wanted to leave me. But she didn’t dare to murder her without assistance. You were to lend the professional touch, were you not?”

“And what was my particular contribution?”

His voice was soft and sly: “You provided the scapegoat, Mr. Archer. No doubt Maude drowned mother herself; she wouldn’t delegate that task, not she. You were there to make sure that Reavis took the blame. My suspicion was confirmed yesterday when Reavis’s cap was found in the grove by the pool. I knew that Reavis didn’t leave it there. He’d left it on the front seat of the car. I saw it in the car myself. I suggest that you saw it there too, and realized what could be done with it.”

“I’m not very suggestible, Mr. Slocum. But let’s assume that what you say is true. What are you going to do about it?”

“There is nothing I can do.” With his eyes turned up toward the ceiling, his hands now gripping each other, he looked like a mad saint. “In order to have you punished, I should have to trumpet my shame, my wife’s shame, to the world. You can rest easy, unless you have a conscience. Last night I did my duty to my dead mother. I told my wife what I have told you. She killed herself. It was fitting.”

Hard words rose in me. I held them back with clenched teeth. Slocum had retreated from reality. If I told him that he had driven his wife to suicide for no good reason, it would only drive him further into the unreal world.

Maude Slocum hadn’t killed herself because she murdered her mother-in-law. Her husband’s story of the cap had simply told her that Reavis hadn’t done it. Which meant that someone else had.

I said to Marvell: “If you care about this man, you’d better get him a damn good doctor.”

He batted his eyes at me, and stuttered something incoherent against his knuckles. Slocum’s face was still turned to the ceiling, wearing a sad holy smile. I went out. Form the hallway I heard him say: “It’s your move, Francis.”

I went through the house alone, thinking of Maude Slocum and looking for her daughter. The rooms and corridors were empty and still. The tide of violence running in the house had permanently ebbed and drawn the life out with it. The veranda and the loggia and the terraces were empty of life, except for the flowers burning in the fading light. I avoided the pool, which glimmered through the trees like a wicked blade. At the end of the funereal alley of cypresses I came to the old lady’s garden.

Cathy was sitting on a stone bench islanded among the lake of flowers. Her face was turned to the west, where a while before the sun had died in a glory. Her young look traveled up beyond the fieldstone wall of the garden to the mountains. She was watching their purple masses as if they formed the walls of a great prison where she had been sentenced to live alone forever.

I called to her over the gate: “Cathy. May I come in?”

She turned slowly, the mountains huge and ancient in her eyes. Her voice was flat: “Hello, Mr. Archer. Do come in.”

I released the redwood latch and stepped into the garden.

“Don’t close it,” she said. “You can leave it open.”

“What are you doing?”

“Just thinking.” She moved aside on the bench, to make room for me. The concrete surface still held the sun’s heat.

“What about?”

“Me. I used to think this was all so beautiful, and now it doesn’t mean a thing. Coleridge was right about nature, I guess. You see the beauty there if you have it in your heart. If your heart is desolate, the world is a wilderness. Did you ever read his ‘Ode to Dejection’?”

I said I never had.

“I understand it now. I’d kill myself if I had my mother’s courage. As it is, I suppose I’ll sit around and wait for something to happen to me. Something good or something bad, it doesn’t really matter.”

I didn’t know what to say. I settled for something meaningless and soothing: “All the bad things have happened, haven’t they?”

“Except the desolation in the heart.” If she hadn’t been completely earnest, the phrase would have sounded foolish.

I said: “Talk it out to me.”

“What do you mean?”

She met my gaze. For a long moment we looked at each other. Her body narrowed and shrunk, drawing away from me. “I don’t know what you mean.”

“You killed your grandmother,” I said. “You might as well tell me about it.”

She bowed her head and shoulders and sat there, dry-eyed and quiet. “Does everybody know?”

“Nobody knows, Cathy. Just me and Ralph Knudson.”

“Yes. He talked to me today. Mr. Knudson is my father. Why didn’t they tell me sooner? I’d never have sent that letter.”

“Why did you send it?” I said.

“I hated my mother. She was cheating on my father—Mr. Slocum. I saw her and Mr. Knudson together one day, and I wanted to make her suffer. And I thought if my father—if Mr. Slocum found out he’d make her leave and we could be together. Don’t you see, they were always quarreling or giving each other the silent treatment. I wanted them separated so there would be some peace. But the letter didn’t seem to make any difference at all.”

For a while she had seemed a woman; more than that, an ageless sybil speaking from ancient wisdom. She had become a child again, a harried child trying to explain the inexplicable: how one could do a murder with the best intentions in the world.
