Frank Abbott nodded.

‘No – we checked it all up – he couldn’t have got to the place where Madoc saw him in the time.’

‘It was abundantly clear,’ said Miss Silver, ‘that Ezra met his death in an attempt to blackmail the murderer. The type of gravel found on his boots showed that it had been picked up on a path in the churchyard or on the drive of one of the houses along the Green. The fact that this gravel was dry and clean was a proof that Ezra did not walk to the miry place where he was found drowned. From the moment Miss Janice informed me of the conversation in which Mr Harsch used some such phrase as “A door opening upon the past” I had a strong conviction that this door had opened in the Ram. Mr Harsch went in there to have tea, and he came out without having it. Why? He missed his train and when he got home he told Miss Madoc that he had seen a ghost. Where? It was clear to me that he had had an encounter which gave him a severe shock, that this encounter was connected with his past life, and that he was not entirely sure that his mind had not been playing him tricks. It was not, of course, someone from Bourne who startled him, but it occurred to me that two persons may have been present, and that one of them may have come from Bourne. If this was the case, both these persons had reason to be very uneasy, and fear lest they should have been recognised may have precipitated the murder.’

Garth Albany said, ‘I don’t think it did. Sir George was coming down next day – they were bound to bump Harsch off before he delivered the goods. Look here, Ida – Miss Mary Anne told you that she had overheard Harsch’s call to Sir George. Did you repeat that to Mr Everton?’

Ida Mottram opened her eyes as wide as they would go.

‘Oh, no, but he was there – we were there together. He was always so very interested about Mr Harsch.’

‘You bet he was!’ said Garth. ‘And you bet he’d have collected the papers if Madoc hadn’t got them off to his bank. He didn’t have to risk getting them on the night of the murder, because he could count on Madoc being pretty sticky about handing them over to Sir George. Sorry, Mrs Madoc, but anyone who knew him could have counted on that.’

On being addressed by what was, after all, her legal name, Medora Madoc blushed painfully. She looked suddenly a good deal younger and, to Garth’s amazement, shy.

Miss Silver inclined her head.

‘I think that is quite true, Major Albany. I believe the plan was to allow Mr Harsch to complete his experiments, and then murder him before he could hand the results over to the government. They knew that the time was running short and they must be ready to act at any moment. The meeting at the Ram may have been for the purpose of handing over a weapon very carefully chosen with a view to suggesting suicide. It is, I think, instructive to look back and see how very near the plan came to succeeding. If it had not been for the fact that Mr Madoc’s conduct exposed him to suspicion, the verdict of suicide would almost certainly have stood, since but for Mr Madoc’s arrest I doubt very much whether Ezra Pincott’s death would have received the attention it deserved. It is reassuring to reflect that criminals so often come to grief over some small happening which they could not have foreseen. Although, Mr Everton’s success and safety depended on his never being suspected. Actually, the very pains he took to avoid suspicion convinced me that there was something to suspect. When Mrs Mottram told him that I was to be called in, there is, I think, no doubt that he took steps to discredit Miss Janice. I have never been able to regard the conversation I heard behind me in the Tube station as fortuitous, I am quite sure that it was carefully planned. He is known to have gone over to Marbury on the Saturday evening, and I have no doubt that he telephoned from there to a confederate in London. It has not, unfortunately, been possible to trace the call. As we now know, Mr Everton’s name is not Everton at all, but Smith. His parents were Germans of the name of Schmidt. He was born and brought up in this country, but paid frequent visits to Germany and became a fanatical Nazi. But-’ she turned graciously to Frank – ‘Sergeant Abbott is better qualified than I am to deal with this.’

‘Well, it’s no secret now. He was up before the magistrates yesterday. The real Everton is still having a nervous breakdown somewhere in Devon. They picked him carefully. He doesn’t seem to have any relations, and his friends were the sort you pick up doing business over a drink or a lunch – easy come, easy go. It was “poor old Everton” for a bit, and then nobody bothered. He’s too bad to write letters. He just dropped clean out. I gather there’s no real likeness between him and Schmidt, but a superficial description of one would fit the other – height, figure, colouring. He seems to have played the part of the cheerful little man with country tastes and a liking for having a finger in everybody’s pie, and to have played it very well indeed.’

Miss Sophy sat up and said, ‘I don’t believe it was a part. I believe it was what he might have been if that wretched Hitler had left him alone. When you think how many, many people were killed in the last war, it does seem a pity Hitler shouldn’t have been one of them.’

Frank Abbott turned an appreciative eye upon her.

‘Thanks for those kind words, Miss Fell.’

With a faint cough Miss Silver resumed.

‘From the moment I had talked with Mrs Mottram it was, of course, clear to me that Mr Everton’s alibi for Tuesday night was no alibi at all. He called Mrs Mottram’s attention to a shot which she did not hear and, looking at his watch, remarked that it was a quarter to ten. Actually, I believe that it was then half-past nine. He ran very little risk, as Mrs Mottram does not wear a watch and has no clock in her drawing-room.’

‘Watches won’t go on me,’ said Ida, looking round for sympathy. ‘They say it’s electricity or something. And I can’t sit in the room with a clock – it worries me. But I’m practically sure I did hear something chime – and of course I thought it was a quarter to ten like he said.’

Miss Silver smiled at her.

‘Yes, my dear – I think he counted on that. He left you at half-past nine, and four or five minutes later he entered the church. I felt sure all along that the murderer was on friendly terms with Mr Harsch, and that some conversation preceded the shot. You see, the curtain which screens the organist was pulled back, and no one seems to have heard the organ later than a very few minutes after half-past nine. Unless the murderer makes a statement, we shall never know quite what happened. But since the appearance of suicide was aimed at, it would be necessary to put Mr Harsch off his guard, and to hold him in conversation until the next set of chimes fell due at a quarter to ten. Schmidt would be watching the time, standing close up to the organ stool. To pass as suicide, the shot must be fired at point-blank range. The three chimes for the quarter begin. At the second he fires. Mr Harsch falls down. Schmidt has only to wipe the weapon, clasp his victim’s hand upon it, and let it drop again, releasing the pistol. If Ezra Pincott had not been in the Church Cut upon his own affairs that night, there is no doubt that a very wicked plan would have succeeded.’

Garth laughed.

‘Ezra was after Giles’ rabbits!’ he said. ‘He could get rabbits anywhere, but it tickled him to get Giles’s – he’d been doing it for years. And a clever old poacher like him wouldn’t be foxed over which side of the road that shot came from. There wasn’t anything about sounds that Ezra wasn’t up to – I’ve been out with him and I know. He told me once he could hear an earwig walking on a leaf, and I believe him.’

‘That is very interesting, Major Albany. To continue. Hearing the shot, Ezra ran to the door in the churchyard wall and opened it. He saw Schmidt leave the church, and ran after him. We know that he caught him up, since Sam and Gladys now say, what would have been more useful if said at once, that, returning from their walk by way of the road which passes the houses, they observed Mr Everton and Ezra in conversation at Mr Everton’s gate. They heard Ezra say, “Drunk or sober, it’ll be something to talk about in the morning”, and he then went off laughing.’
