Poirot interpolated a question. "Supposing, Mr. Clarke, that your brother had been found shot at the foot of a cliff—or shot with a revolver beside him. What would have been your first thought?"

"Quite frankly, I should have jumped to the conclusion that it was suicide," said Clarke.

"Encore.'' said Poirot.

"What is that?"

"A fact that repeats itself. It is of no matter."

"Anyway, it wasn't suicide," said Crome with a touch of curtness. "Now I believe, Mr. Clarke, that it was your brother's habit to go for a stroll every evening?"

"Quite right. He always did."

"Every night?"

"Well, not if it was pouring with rain, naturally."

"And everyone in the house knew of this habit?"

"Of course."

"And outside?"

"I don't quite know what you mean by outside. The gardener may have been aware of it or not, I don't know."

"And in the village?"

"Strictly speaking, we haven't got a village. There's a post office and cottages at Churston Fetters—but there's no village or shops."

"I suppose a stranger hanging round the place would be fairly easily noticed?"

"On the contrary. In August all this part of the world is a seething mass of strangers. They come over every day from Brixham and Torquay and Paignton in cars and buses and on foot. Broadsands, which is down there [he pointed], is a very popular beach and so is Elbury Cove—it's a well-known beauty spot and people come there and picnic. I wish they didn't! You've no idea how beautiful and peaceful this part of the world is in June and the beginning of July."

"So you don't think a stranger would be noticed?"

"Not unless he looked—well, off his head."

"This man doesn't look off his head," said Crome with certainty. "You see what I'm getting at, Mr. Clarke. This man must have been spying out the land beforehand and discovered your brother's habit of taking an evening stroll. I suppose, by the way, that no strange man came up to the house and asked to see Sir Carmichael yesterday?"

"Not that I know of—but we'll ask Deveril."

He rang the bell and put the question to the butler.

"No, sir, no one came to see Sir Carmichael. And I didn't notice anyone hanging about the house either. No more did the maids, because I've asked them."

The butler waited a moment, then inquired: "Is that all, sir?"

"Yes, Deveril, you can go."

The butler withdrew, drawing back in the doorway to let a young woman pass.

Franklin Clarke rose as she came. "This is Miss Grey, gentlemen. My brother's secretary."

My attention was caught at once by the girl's extraordinary Scandinavian fairness. She had the almost colourless ash hair—light grey eyes—and transparent glowing pallor that one finds amongst Norwegians and Swedes. She looked about twenty-seven and seemed to be as efficient as she was decorative.

"Can I help you in any way?" she asked as she sat down.

Clarke brought her a cup of coffee, but she refused any food.

"Did you deal with Sir Carmichael's correspondence?" asked Crome.

"Yes, all of it."

"I suppose he never received a letter or letters signed A.B.C.?"

"A.B.C.?" She shook her head. "No, I'm sure he didn't."

"He didn't mention having seen anyone hanging about during his evening walks lately?"

"No. He never mentioned anything of the kind."

"And you yourself have noticed no strangers?"

"Not exactly hanging about. Of course, there are a lot of people what you might call wandering about at this time of year. One often meets people strolling with an aimless look across the golf links or down the lanes to the sea. In the same way, practically everyone one sees this time of year is a stranger."

Poirot nodded thoughtfully.

Inspector Crome asked to be taken over the ground of Sir Carmichael's nightly walk. Franklin Clarke led the way through the French window, and Miss Grey accompanied us.

She and I were a little behind the others. "All this must have been a terrible shock to you all," I said.

"It seems quite unbelievable. I had gone to bed last night when the police rang up. I heard voices downstairs and at last I came out and asked what was the matter. Deveril and Mr. Clarke were just setting out with lanterns."

"What time did Sir Carmichael usually come back from his walk?"

"About a quarter to ten. He used to let himself in by the side door and then sometimes he went straight to bed, sometimes to the gallery where his collections were. That is why, unless the police had rung up, he would probably not have been missed till they went to call him this morning."

"It must have been a terrible shock to his wife?"

"Lady Clarke is kept under morphine a good deal. I think she is in too dazed a condition to appreciate what goes on round her."

We had come out through a garden gate onto the golf links. Crossing a corner of them, we passed over a stile into a steep, winding lane.

"This leads down to Elbury Cove," explained Franklin Clarke. "But two years ago they made a new road leading from the main road to Broadsands and on to Elbury, so that now this lane is practically deserted.''

We went on down the lane. At the foot of it a path led between brambles and bracken down to the sea. Suddenly we came out on a grassy ridge overlooking the sea and a beach of glistening white stones. All round dark green trees ran down to the sea. It was an enchanting spot—white, deep green and sapphire blue.

"How beautiful!" I exclaimed.

Clarke turned to me eagerly. "Isn't it? Why people want to go abroad to the Riviera when they've got this! I've wandered all over the world in my time and, honest to God, I've never seen anything as beautiful."

Then, as though ashamed of his eagerness, he said in a more matter-of-fact tone: "This was my brother's evening walk. He came as far as here, then back up the path, and turning to the right instead of the left, went past the farm and across the fields back to the house."

We proceeded on our way till we came to a spot near the hedge, halfway across the field where the body had been found.

Crome nodded. "Easy enough. The man stood here in the shadow. Your brother would have noticed nothing till the blow fell." The girl at my side gave a quick shiver.

Franklin Clarke said: "Hold up, Thora. It's pretty beastly, but it's no use shirking facts."

Thora Grey—the name suited her.

We went back to the house where the body had been taken after being photographed.

As we mounted the wide staircase the doctor came out of a room, black bag in hand.

"Anything to tell us, doctor?" inquired Clarke.

The doctor shook his head. "Perfectly simple case. I'll keep the technicalities for the inquest. Anyway, he didn't suffer. Death must have been instantaneous."

He moved away. "I'll just go in and see Lady Clarke."

A hospital nurse came out of a room further along the corridor and the doctor joined her.

We went into the room out of which the doctor had come.

I came out again rather quickly. Thora Grey was still standing at the head of the stairs.

There was a queer scared expression on her face. "Miss Grey—" I stopped. "Is anything the matter?"

She looked at me. "I was thinking," she said—"about D."

"About D?" I stared at her stupidly.
