Constable Melkinthorpe then drove away, asking the Chief Inspector, as he halted the car in the Vicarage gateway, which way he was to go. He was told to drive to Rose Cottages, and, after allowing a boy on a bicycle to pass down the High Street, he swung his wheel over to the left, and was just changing gear when the Chief Inspector told him to stop. He obediently pulled in to the side of the street, and saw Major Midgeholme crossing the road towards the car.

“Good-evening, sir!” said Hemingway. “Want me?”

“Yes,” said the Major, with an air of resolution. “I have been turning it over in my mind, and I think it's my duty to put you in possession of a piece of information. Mind you, it may be nothing! I don't say I attach much importance to it, but one never knows, and in such cases as this I consider it to be every man's duty to tell the police whatever he may know.”

“Quite right, sir,” said Hemingway, and waited.

But the Major seemed still to be a little undecided. “Can't say I like talking about my neighbours!” he said. “But when it comes to murder, things are different. My feeling is that if what I have to say is irrelevant, there's no harm done; and if it isn't—well! There's no denying that this business has made us all sit up—do a bit of thinking! I'm not going to pretend I know who did it, because I don't. Between you and me and the gate-post, there's a bit too much amateur detection going on in Thornden! Shouldn't like you to think I was trying to do your job for you, but of course I've thought about it a good deal, and talked it over with one or two people. As a matter of fact, I was discussing it with my wife last night—she's got her own theories, but I shan't go into that, for I don't agree with her. Point is, it's been in my mind all along that the two people who disliked Warrenby the most were Drybeck and Plenmeller. Now, when Drybeck and I were on our way to The Cedars on Saturday, Plenmeller joined us, and one of the things he said was that his was the only threshold in Thornden which Warrenby couldn't cross.” The Major paused impressively. “Well, I happened to mention that to my wife, and she told me that she had seen Warrenby go into Thornden House on Saturday morning! Of course, she doesn't know what he went for, or for how long he was with Plenmeller, for she was shopping, and she thought no more about it. I didn't set much store by it myself when she first told me, but I've been turning it over in my mind, and I've come to the conclusion you ought to know about it. As I say, there may be nothing in it. On the other hand, queer thing to do—boast that Warrenby had never crossed his threshold when he'd done so that very morning! Almost as if he wanted to make sure no one should think he'd had any dealings with the fellow.”

Constable Melkinthorpe, glancing at the Chief Inspector to see what effect this disclosure had upon him was not surprised to perceive that his calm was quite unruffled.

“I see,” said Hemingway, gravely. “He'd have to be a bit of an optimist, wouldn't he, sir to think no one would notice Mr. Warrenby going to call on him, on a Saturday morning, right on the village street?”

“Well,” said the Major, shrugging, “I've told you for what it's worth, that's all!” He looked up, and stiffened a little. Gavin Plenmeller, coming from the direction of his house, was crossing the road diagonally towards them.

“Undergoing interrogation, laying information, or just passing the time of day, Major?” enquired Gavin. “I'm glad to see you here, Chief Inspector, and I'm sure the whole village shares my feeling. We confidently expected to see you in our midst at crack of dawn, but it was not to be. I may add that a certain amount of dissatisfaction has been felt. Action is what we want, and we did think that a real detective from London would provide us with plenty to talk about.”

“Well, I must be getting along,” said the Major, not quite comfortably.
