It was nearer seven than half-past six when I approached the Vicarage gate on my return. Before I reached it, it swung open and Lawrence Redding came out. He stopped dead on seeing me, and I was immediately struck by his appearance. He looked like a man who was on the point of going mad. His eyes stared in a peculiar manner, he was deathly white, and he was shaking and twitching all over.

I wondered for a moment whether he could have been drinking, but repudiated the idea immediately

"Hullo," I said, "have you been to see me again? Sorry I was out. Come back now. I've got to see Protheroe about some accounts - but I dare say we shan't be long."

"Protheroe," he said. He began to laugh. "Protheroe? You're going to see Protheroe? Oh! you'll see Protheroe all right. Oh! my God - yes."

I stared. Instinctively I stretched out a hand towards him. He drew sharply aside.

"No," he almost cried out. "I've got to get away - to think. I've got to think. I must think."

He broke into a run and vanished rapidly down the road towards the village, leaving me staring after him, my first idea of drunkenness recurring.

Finally I shook my head, and went on to the Vicarage. The front door is always left open, but nevertheless I rang the bell. Mary came, wiping her hands on her apron.

"So you're back at last," she observed.

"Is Colonel Protheroe here?" I asked.

"In the study. Been here since a quarter past six."

"And Mr. Redding's been here?"

"Come a few minutes ago. Asked for you. I told him you'd be back any minute and that Colonel Protheroe was waiting in the study, and he said he'd wait too, and went there. He's there now."

"No, he isn't," I said. "I've just met him going down the road."

"Well, I didn't hear him leave. He can't have stayed more than a couple of minutes. The mistress isn't back from town yet."

I nodded absentmindedly. Mary beat a retreat to the kitchen quarters and I went down the passage and opened the study door.

After the dusk of the passage, the evening sunshine that was pouring into the room made my eyes blink. I took a step or two across the floor and then stopped dead.

For a moment I could hardly take in the meaning of the scene before me.

Colonel Protheroe was lying sprawled across my writing table in a horrible unnatural position. There was a pool of some dark fluid on the desk by his head, and it was slowly dripping on to the floor with a horrible drip, drip, drip.

I pulled myself together and went across to him. His skin was cold to the touch. The hand that I raised fell back lifeless. The man was dead - shot through the head.

I went to the door and called Mary. When she came I ordered her to run as fast as she could and fetch Dr. Haydock, who lives just at the corner of the road. I told her there had been an accident.

Then I went back and closed the door to await the doctor's coming.

Fortunately, Mary found him at home. Haydock is a good fellow, a big, fine, strapping man with an honest, rugged face.

His eyebrows went up when I pointed silently across the room. But, like a true doctor, he showed no signs of emotion. He bent over the dead man, examining him rapidly. Then he straightened himself and looked across at me.

"Well?" I asked.

"He's dead right enough - been dead half an hour, I should say."

"Suicide?"

"Out of the question, man. Look at the position of the wound. Besides, if he shot himself, where's the weapon?"

True enough, there was no sign of any such thing.

"We'd better not mess around with anything," said Haydock. "I'd better ring up the police."

He picked up the receiver and spoke into it. He gave the facts as curtly as possible and then replaced the telephone and came across to where I was sitting.

"This is a rotten business. How did you come to find him?"

I explained. "Is - is it murder?" I asked rather faintly.

"Looks like it. Mean to say, what else can it be? Extraordinary business. Wonder who had a down on the poor old fellow. Of course I know he wasn't popular, but one isn't often murdered for that reason - worse luck."

"There's one rather curious thing," I said. "I was telephoned for this afternoon to go to a dying parishioner. When I got there every one was very surprised to see me. The sick man was very much better than he had been for some days, and his wife flatly denied telephoning for me at all."

Haydock drew his brows together.

"That's suggestive - very. You were being got out of the way. Where's your wife?"

"Gone up to London for the day."

"And the maid?"

"In the kitchen - right at the other side of the house."

"Where she wouldn't be likely to hear anything that went on in here. It's a nasty business. Who knew that Protheroe was coming here this evening?"

"He referred to the fact this morning in the village street at the top of his voice as usual."

"Meaning that the whole village knew it? Which they always do in any case. Know of any one who had a grudge against him? "

The thought of Lawrence Redding's white face and staring eyes came to my mind. I was spared answering by a noise of shuffling feet in the passage outside.

"The police," said my friend, and rose to his feet.

Our police force were represented by Constable Hurst, looking very important but slightly worried.

"Good-evening, gentlemen," he greeted us. "The Inspector will be here any minute. In the meantime I'll follow out his instructions. I understand Colonel Protheroe's been found shot - in the Vicarage."

He paused and directed a look of cold suspicion at me, which I tried to meet with a suitable bearing of conscious innocence.

He moved over to the writing table and announced:

"Nothing to be touched until the Inspector comes."

For the convenience of my readers I append a sketch plan of the room.

He got out his notebook, moistened his pencil and looked expectantly at both of us.

I repeated my story of discovering the body. When he had got it all down, which took some time, he turned to the doctor.

"In your opinion, Dr. Haydock, what was the cause of death?"

"Shot through the head at close quarters."

"And the weapon?"

"I can't say with certainty until we get the bullet out. But I should say in all probability the bullet was fired from a pistol of small calibre - say a Mauser.25."

I started, remembering our conversation of the night before, and Lawrence Redding's admission. The police constable brought his cold, fish-like eye round on me.

"Did you speak, sir?"

I shook my head. Whatever suspicions I might have, they were no more than suspicions, and as such to be kept to myself.

"When, in your opinion, did the tragedy occur?"

The doctor hesitated for a minute before he answered. Then he said:

"The man has been dead just over half an hour, I should say. Certainly not longer."

Hurst turned to me. "Did the girl hear anything?"

"As far as I know she heard nothing," I said. "But you bad better ask her."

But at this moment Inspector Slack arrived, having come by car from Much Benham, two miles away.

All that I can say of Inspector Slack is that never did a man more determinedly strive to contradict his name. He was a dark man, restless and energetic in manner, with black eyes that snapped ceaselessly. His manner was rude and overbearing in the extreme.

He acknowledged our greetings with a curt nod, seized his subordinate's notebook, perused it, exchanged a few curt words with him in an undertone, then strode over to the body.

"Everything's been messed up and pulled about, I suppose," he said.

"I've touched nothing," said Haydock.
