'"She would be," I said. "They would start by being quite like mushrooms in appearance, and they would end by being orange with purple spots. There is nothing that class cannot remember if it tries."
'I gathered that Denman had been past speech when the doctor got to him. He was incapable of swallowing, and had died within a few minutes. The doctor seemed perfectly satisfied with the certificate he had given. But how much of that was obstinacy and how much of it was genuine belief I could not be sure.
'I went straight home and asked Mabel quite frankly why she had bought arsenic.
'"You must have had some idea in your mind," I pointed out.
'Mabel burst into tears. "I wanted to make away with myself," she moaned. "I was too unhappy. I thought I would end it all."
'"Have you the arsenic still?" I asked.
'"No, I threw it away."
'I sat there turning things over and over in my mind.
'"What happened when he was taken ill? Did he call you?"
'"No." She shook her head. "He rang the bell violently. He must have rung several times. At last Dorothy, the house-parlourmaid, heard it, and she waked the cook up, and they came down. When Dorothy saw him she was frightened. He was rambling and delirious. She left the cook with him and came rushing to me. I got up and went to him. Of course I saw at once he was dreadfully ill. Unfortunately Brewster, who looks after old Mr Denman, was away for the night, so there was no one who knew what to do. I sent Dorothy off for the doctor, and cook and I stayed with him, but after a few minutes I couldn't bear it any longer; it was too dreadful. I ran away back to my room and locked the door."
'"Very selfish and unkind of you," I said; "and no doubt that conduct of yours has done nothing to help you since, you may be sure of that. Cook will have repeated it everywhere. Well, well, this is a bad business."
'Next I spoke to the servants. The cook wanted to tell me about the mushrooms, but I stopped her. I was tired of these mushrooms. Instead, I questioned both of them very closely about their master's condition on that night They both agreed that he seemed to be in great agony, that he was unable to swallow, and he could only speak in a strangled voice, and when he did speak it was only rambling - nothing sensible.
'"What did he say when he was rambling?" I asked curiously.
'"Something about some fish, wasn't it?" turning to the other.
'Dorothy agreed.
'"A heap of fish," she said; "some nonsense like that. I could see at once he wasn't in his right mind, poor gentleman."
'There didn't seem to be any sense to be made out of that. As a last resource I went up to see Brewster, who was a gaunt, middle-aged woman of about fifty.
'"It is a pity that I wasn't here that night," she said, "Nobody seems to have tried to do anything for him
until the doctor came."
'"I suppose he was delirious," I said doubtfully, "but that is not a symptom of ptomaine poisoning, is it?"
'"It depends," said Brewster.
'I asked her how her patient was getting on.
'She shook her head.
'"He is pretty bad," she said.
'"Weak?"
'"Oh no, he is strong enough physically - all but his eyesight. That is failing badly. He may outlive all of us, but his mind is failing very fast now. I have already told both Mr and Mrs Denman that he ought to be in an institution, but Mrs Denman wouldn't hear of it at any price."
'I will say for Mabel that she always had a kindly heart.
'Well, there the thing was. I thought it over in every aspect, and at last I decided that there was only one thing to be done. In view of the rumours that were going about, permission must be applied for to exhume the body, and a proper post-mortem must be made and lying tongues quietened once and for all. Mabel, of course, made a fuss, mostly on sentimental grounds - disturbing the dead man in his peaceful grave, etc., etc. - but I was firm.
'I won't make a long story of this part of it. We got the order and they did the autopsy, or whatever they call it, but the result was not so satisfactory as it might have been. There was no trace of arsenic - that was all to the good - but the actual words of the report were that there was nothing to show by what means deceased had come to his death.
'So, you see, that didn't lead us out of trouble altogether. People went on talking - about rare poisons impossible to detect, and rubbish of that sort. I had seen the pathologist who had done the post-mortem, and I had asked him several questions, though he tried his best to get out of answering most of them; but I got out of him that he considered it highly unlikely that the poisoned mushrooms were the cause of death. An idea was simmering in my mind, and I asked him what poison, if any, could have been employed to obtain that result He made a long explanation to me, most of which, I must admit, I did not follow, but it amounted to this: That death might have been due to some strong vegetable alkaloid.
'The idea I had was this: Supposing the taint of insanity was in Geoffrey Denman's blood also, might he not have made away with himself? He had, at one period of his life, studied medicine, and he would have a good knowledge of poisons and their effects.
'I didn't think it sounded very likely, but it was the only thing I could think of. And I was nearly at my wits' end, I can tell you. Now, I dare say you modern young people will laugh, but when I am in really bad trouble I always say a little prayer to myself - anywhere, when I am walking along the street, or at a bazaar. And I always get an answer. It may be some trifling thing, apparently quite unconnected with the subject, but there it is. I had that text pinned over my bed when I was a little girclass="underline" Ask and you shall receive. On the morning that I am telling you about, I was walking along the High Street, and I was praying hard. I shut my eyes, and when I opened them, what do you think was the first thing that I saw?'
Five faces with varying degrees of interest were turned to Miss Marple. It may be safely assumed, however, that no one would have guessed the answer to the question right.
'I saw,' said Miss Marple impressively, 'the window of the fishmonger's shop. There was only one thing in it, a fresh haddock.'
She looked round triumphantly.
'Oh, my God!' said Raymond West. 'An answer to prayer - a fresh haddock!'
'Yes, Raymond,' said Miss Marple severely, 'and there is no need to be profane about it The hand of God is everywhere. The first thing I saw were the black spots - the marks of St Peter's thumb. That is the legend, you know. St Peter's thumb. And that brought things home to me. I needed faith, the ever true faith of St Peter. I connected the two things together, faith - and fish.'
Sir Henry blew his nose rather hurriedly. Joyce bit her lip.
'Now what did that bring to my mind? Of course, both the cook and house-parlourmaid mentioned fish as being one of the things spoken of by the dying man. I was convinced, absolutely convinced, that there was some solution of the mystery to be found in these words. I went home determined to get to the bottom of the matter.'
She paused.
'Has it ever occurred to you,' the old lady went on, 'how much we go by what is called, I believe, the context? There is a place on Dartmoor called Grey Wethers. If you were talking to a farmer there and mentioned Grey Wethers, he would probably conclude that you were speaking of these stone circles, yet it is possible that you might be speaking of the atmosphere; and in the same way, if you were meaning the stone circles, an outsider, hearing a fragment of the conversation, might think you meant the weather. So when we repeat a conversation, we don't, as a rule, repeat the actual words; we put in some other words that seem to us to mean exactly the same thing.
