Miss Marple's final cases

'That was our first line of enquiry,' said Mr Petherick. 'Mary Hill is a local woman. She had been chambermaid at the Crown for ten years. There seems absolutely no reason why she should commit a sudden assault on a guest. She is, in any case, extraordinarily stupid, almost half-witted. Her story has never varied. She brought Mrs Rhodes her hot water bottle and says the lady was drowsy - just dropping off to sleep. Frankly, I cannot believe, and I am sure no jury would believe, that she committed the crime.'

Mr Petherick went on to mention a few additional details. At the head of the staircase in the Crown Hotel is a kind of miniature lounge where people sometimes sit and have coffee. A passage goes off to the right and the last door in it is the door into the room occupied by Mr Rhodes. The passage then turns sharply to the right again and the first door round the corner is the door into Mrs Rhodes's room. As it happened, both these doors could be seen by witnesses. The first door - that into Mr Rhodes's room, which I will call A, could be seen by four people, two commercial travellers and an elderly married couple who were having coffee. According to them nobody went in or out of door A except Mr Rhodes and the chambermaid. As to the other door in the passage B, there was an electrician at work there and he also swears that nobody entered or left door B except the chambermaid.

It was certainly a very curious and interesting case. On the face of it, it looked as though Mr Rhodes must have murdered his wife. But I could see that Mr Petherick was quite convinced of his client's innocence and Mr Petherick was a very shrewd man.

At the inquest Mr Rhodes had told a hesitating and rambling story about some woman who had written threatening letters to his wife. His story, I gathered, had been unconvincing in the extreme. Appealed to by Mr Petherick, he explained himself.

'Frankly,' he said, 'I never believed it. I thought Amy had made most of it up.'

Mrs Rhodes, I gathered, was one of those romantic liars who go through life embroidering everything that happens to them. The amount of adventures that, according to her own account, happened to her in a year was simply incredible. If she slipped on a bit of banana peel it was a case of near escape from death. If a lampshade caught fire she was rescued from a burning building at the hazard of her life. Her husband got into the habit of discounting her statements. Her tale as to some woman whose child she had injured in a motor accident and who had vowed vengeance on her - well - Mr Rhodes had simply not taken any notice of it. The incident had happened before he married his wife and although she had read him letters couched in crazy language, he had suspected her of composing them herself. She had actually done such a thing once or twice before. She was a woman of hysterical tendencies who craved ceaselessly for excitement.

Now, all that seemed to me very natural - indeed, we have a young woman in the village who does much the same thing. The danger with such people is that when anything at all extraordinary really does happen to them, nobody believes they are speaking the truth. It seemed to me that that was what had happened in this case. The police, I gathered, merely believed that Mr Rhodes was making up this unconvincing tale in order to avert suspicion from himself.

I asked if there had been any women staying by themselves in the hotel. It seemed there were two - a Mrs Granby, an Anglo-Indian widow, and a Miss Carruthers, rather a horsey spinster who dropped her g's. Mr Petherick added that the most minute enquiries had failed to elicit anyone who had seen either of them near the scene of the crime and there was nothing to connect either of them with it in any way. I asked him to describe their personal appearance. He said that Mrs Granby had reddish hair rather untidily done, was sallow-faced and about fifty years of age. Her clothes were rather picturesque, being made mostly of native silk, etc. Miss Carruthers was about forty, wore pince-nez, had close cropped hair like a man and wore mannish coats and skirts.

'Dear me,' I said, 'that makes it very difficult.'

Mr Petherick looked enquiringly at me, but I didn't want to say any more just then, so I asked what Sir Malcolm Olde had said.

Sir Malcolm was confident of being able to call conflicting medical testimony and to suggest some way of getting over the fingerprint difficulty. I asked Mr Rhodes what he thought and he said all doctors were fools but he himself couldn't really believe that his wife had killed herself. 'She wasn't that kind of woman,' he said simply - and I believed him. Hysterical people don't usually commit suicide.

I thought a minute and then I asked if the door from Mrs Rhodes's room led straight into the corridor. Mr Rhodes said no - there was a little hallway with bathroom and lavatory. It was the door from the bedroom to the hallway that was locked and bolted on the inside.
