Halliday’s consulting him. He had confidence in Kennedy’s medical knowledge-and the suggestion that his wife was drugging him was very cleverly put to him by Kennedy.’
‘But could any drug make a man have the hallucination that he was strangling his wife?’ asked Giles. ‘I mean there isn’t any drug, is there, that has thatparticular effect?’
‘My dear Giles, you’ve fallen into the trap again-the trap of believing what is said to you. There is only Dr Kennedy’s word for it that Halliday ever had that hallucination. He himself never says so in his diary. He had hallucinations, yes, but he does not mention their nature. But I dare say Kennedy talked to him about men who had strangled their wives after passing through a phase such as Kelvin Halliday was experiencing.’
‘Dr Kennedy was really wicked,’ said Gwenda.
‘I think,’ said Miss Marple, ‘that he’d definitely passed the borderline between sanity and madness by that time. And Helen, poor girl, began to realize it. It was to her brother she must have been speaking that day when she was overheard by Lily. ‘I think I’ve always been afraid of you.’ That was one of the things she said. And that always was very significant. And so she determined to leave Dillmouth. She persuaded her husband to buy a house in Norfolk, she persuaded him not to tell anyone about it. The secrecy about it was very illuminating. She was clearly very afraid of someone knowing about it-but that did not fit in with the Walter Fane theory or the Jackie Afflick theory-and certainly not with Richard Erskine’s being concerned. No, it pointed to somewhere much nearer home.
‘And in the end, Kelvin Halliday, whom doubtless the secrecy irked and who felt it to be pointless, told his brother-in-law.
‘And in so doing, sealed his own fate and that of his wife. For Kennedy was not going to let Helen go and live happily with her husband. I think perhaps his idea was simply to break down Halliday’s health with drugs. But at the revelation that his victim and Helen were going to escape him, he became completely unhinged. From the hospital he went through into the garden of St Catherine’s and he took with him a pair of surgical gloves. He caught Helen in the hall, and he strangled her. Nobody saw him, there was no one there to see him, or so he thought, and so, racked with love and frenzy, he quoted those tragic lines that were so apposite.’
Miss Marple sighed and clucked her tongue.
‘I was stupid-very stupid. We were all stupid. We should have seen at once. Those lines from The Duchess of Malfi were really the clue to the whole thing. They are said, are they not, by a brother who has just contrived his sister’s death to avenge her marriage to the man she loved. Yes, we were stupid-’
‘And then?’ asked Giles.
‘And then he went through with the whole devilish plan. The body carried upstairs. The clothes packed in a suitcase. A note, written and thrown in the wastepaper basket to convince Halliday later.’
‘But I should have thought,’ said Gwenda, ‘that it would have been better from his point of view for my father actually to have been convicted of the murder.’
Miss Marple shook her head.
‘Oh no, he couldn’t risk that. He had a lot of shrewd Scottish common sense, you know. He had a wholesome respect for the police. The police take a lot of convincing before they believe a man guilty of murder. The police might have asked a lot of awkward questions and made a lot of awkward enquiries as to times and places. No, his plan was simpler and, I think, more devilish. He only had Halliday to convince. First, that he had killed his wife. Secondly that he was mad. He persuaded Halliday to go into a mental home, but I don’t think he really wanted to convince him that it was all a delusion. Your father accepted that theory, Gwennie, mainly, I should imagine, for your sake. He continued to believe that he had killed Helen. He died believing that.’
‘Wicked,’ said Gwenda. ‘Wicked-wicked-wicked.’
‘Yes,’ said Miss Marple. ‘There isn’t really any other word. And I think, Gwenda, that that is why your childish impression of what you saw remained so strong. It was real evil that was in the air that night.’
‘But the letters,’ said Giles. ‘Helen’s letters? Theywere in her handwriting, so they couldn’t be forgeries.’
‘Of course they were forgeries! But that is where he overreached himself. He was so anxious, you see, to stop you and Giles making investigations. He could probably imitate Helen’s handwriting quite nicely-but it wouldn’t fool an expert. So the sample of Helen’s handwriting he sent you with the letter wasn’t her handwriting either. He wrote it himself. So naturally it tallied.’
‘Goodness,’ said Giles. ‘I never thought of that.’
‘No,’ said Miss Marple. ‘You believed what he said. It really is very dangerous to believe people. I never have for years.’
‘And the brandy?’
‘He did that the day he came to Hillside with Helen’s letter and talked to me in the garden. He was waiting in the house while Mrs Cocker came out and told me he was there. It would only take a minute.’
‘Good Lord,’ said Giles. ‘And he urged me to take Gwenda home and give her brandy after we were at the police station when Lily Kimble was killed. How did he arrange to meet her earlier?’
‘That was very simple. The original letter he sent her asked her to meet him at Woodleigh Camp and come to Matchings Halt by the two-five train from Dillmouth Junction. He came out of the copse of trees, probably, and accosted her as she was going up the lane-and strangled her. Then he simply substituted the letter you all saw for the letter she had with her (and which he had asked her to bring because of the directions in it) and went home to prepare for you and play out the little comedy of waiting for Lily.’
‘And Lily really was threatening him? Her letter didn’t sound as though she was. Her letter sounded as though she suspected Afflick.’
‘Perhaps she did. But Leonie, the Swiss girl, had talked to Lily, and Leonie was the one danger to Kennedy. Because she looked out of the nursery window and saw him digging in the garden. In the morning he talked to her, told her bluntly that Major Halliday had killed his wife-that Major Halliday was insane, and that he, Kennedy, was hushing up the matter for the child’s sake. If, however, Leonie felt she ought to go to the police, she must do so, but it would be very unpleasant for her-and so on.
‘Leonie took immediate fright at the mention of the police. She adored you and had implicit faith in what M. le docteur thought best. Kennedy paid her a handsome sum of money and hustled her back to Switzerland. But before she went, she hinted something to Lily as to your father’s having killed his wife and that she had seen the body buried. That fitted in with Lily’s ideas at the time. She took it for granted that it was Kelvin Halliday Leonie had seen digging the grave.’
‘But Kennedy didn’t know that, of course,’ said Gwenda.
‘Of course not. When he got Lily’s letter the words in it that frightened him were that Leonie had told Lily what she had seen out of the window and the mention of the car outside.’
‘The car? Jackie Afflick’s car?’
‘Another misunderstanding. Lily remembered, or thought she remembered, a car like Jackie Afflick’s being outside in the road. Already her imagination had got to work on the Mystery Man who came over to see Mrs Halliday. With the hospital next door, no doubt a good many cars did park along this road. But you must remember that the doctor’s car was actually standing outside the hospital that night-he probably leaped to the conclusion that she mean this car. The adjective posh was meaningless to him.’
‘I see,’ said Giles. ‘Yes, to a guilty conscience that letter of Lily’s might look like blackmail. But how do you know all about Leonie?’
Her lips pursed close together, Miss Marple said: ‘He went-right over the edge, you know. As soon as the men Inspector Primer had left rushed in and seized him, he went over the whole crime again and again-everything he’d done. Leonie died, it seems, very shortly after her return to Switzerland. Overdose of some sleeping tablets…Oh no, he wasn’t taking any chances.’
‘Like trying to poison me with the brandy.’
‘You were very dangerous to him, you and Giles. Fortunately you never told him about your memory of seeing Helen dead in the hall. He never knew there had been an eye-witness.’
‘Those telephone calls to Fane and Afflick,’ said Giles. ‘Did he put those through?’
‘Yes. If there was an enquiry as to who could have tampered with the brandy, either of them would make an admirable suspect, and if Jackie Afflick drove over in his car alone, it might tie him in with Lily Kimble’s murder. Fane would most likely have an alibi.’
