'Oh, I've got one all right.' Mr. Bradley smiled in a superior manner. This was the first time he had succeeded in provoking Miss Dammers to snap at him, and he was rather pleased. 'But let's take things in their proper order. I want to show you how inevitably I was led to my conclusion, and I can only do that by tracing out my own footsteps, so to speak. Having made my deductions from the poison itself, then, I set about examining the other clues to see if they would lead me to a result that I could check by the other. First of all I concentrated on the notepaper of the forged letter, the only really valuable clue apart from the poison.
'Now this piece of notepaper puzzled me. For some reason, which I couldn't identify, the name of Mason's seemed to strike a reminiscent note to me. I felt sure that I'd heard of Mason's in some other connection than just through their excellent chocolates. At last I remembered.
'I'm afraid I must touch here on the personal, and I apologise in advance, Sir Charles, for the lapse of taste. My sister, before she married, was a shorthand typist.' Mr. Bradley's extreme languor all of a sudden indicated that he felt this connection needed some defence and was determined not to give it. The next instant he gave it. 'That is to say, her education put her on rather a different level from the usual shorthand - typist, and she was, in point of fact, a trained secretary.
'She had joined an establishment run by a lady who supplied secretaries to business firms to take the places temporarily of girls in responsible positions who were ill, or away on holiday, or anything like that. Including my sister there were only two or three girls at the place, and the posts they went to only lasted as a rule for two or three weeks. Each girl would therefore have a good many such posts in the course of a year. However, I did remember distinctly that one of the firms to which my sister went while she was there was Mason's, as temporary secretary to one of the directors.
'This seemed to me possibly useful. It wouldn't be likely that she could throw a sidelight on the murder, but at any rate she might be able to give me introductions to one or two members of Mason's staff if necessary. So I went down to see her about it.
'She remembered quite well. It was between three and four years ago, and she liked being there so much that she had thought quite seriously of putting in for a permanent secretaryship with the firm, should one be available. Naturally she hadn't got to know any of the staff really well, but quite enough to give me the introductions if I wanted them.
''By the way,' I happened to say to her casually, 'I saw the letter that was sent to Sir Eustace with the chocolates, and not only Mason's name but the actual paper itself struck me as familiar. I suppose you wrote to me on it while you were there?'
''I don't know that I ever did that,' she said, 'but, of course, the paper was familiar to you. You've played paper - games here often enough, haven't you? You know we always use it. It's such a convenient size.' Paper - games, I should explain, have always been a favourite thing in our family.
'It's funny how a connection will stick in the mind, but not the actual circumstances of it. Of course I remembered then at once. There was quite a pile of the paper, in one of the drawers of my sister's writing - table. I'd often torn it into strips for our paper - games myself.
''But how did you get hold of it?' I asked her.
'It seemed to me that she answered rather evasively, just saying that she'd got it from the office when she was working there. I pressed her, and at last she told me that one evening she was just on the point of leaving the office when she remembered that some friends were coming in after dinner at home. We should almost certainly play a paper - game of some kind, and we had run out of suitable paper. She hurried up the stairs again back to the office, dumped her attache - case on the table and opened it, hastily snatched up some paper from the pile beside her typewriter, and threw it into the case. In her hurry she didn't realise how much she'd taken, and that supply, which was supposed to tide us over one evening, had actually lasted for nearly four years. She must have taken something like half a ream.
'Well, I went away from my sister's house rather startled. Before I left I examined the remaining sheets, and so far as I could see they were exactly like the one on which the letter was typed. Even the edges were a little discoloured too. I was more than startled: I was alarmed. Because I ought to tell you that it had already occurred to me that of all the ways of going about the search for the person who had sent that letter to Sir Eustace, the one that seemed most hopeful was to look for its writer among the actual employees, or ex - employees, of the firm itself.
'As a matter of fact this discovery of mine had a more disconcerting side still. On thinking over the case the idea had struck me that in the two matters of the notepaper and the method itself of the crime it was quite possible that the police, and every one else had been putting the cart before the horse. It had been taken for granted apparently that the murderer had first of all decided on the method, and then set about getting hold of the notepaper to carry it out.
'But isn't it far more feasible that the notepaper should have been already there, in the criminal's ownership, and that it was the chance possession of it which actually suggested the method of the crime? In that case, of course, the likelihood of the notepaper being traced to the murderer would be very small indeed, whereas in the other case there is always that possibility. Had that occurred to you for instance, Mr. President?'
'I must admit that it hadn't,' Roger confessed. 'And yet, like Holmes's tricks, the possibility's evident enough now it's brought forward. I must say, it strikes me as being a very sound point, Bradley.'
'Psychologically, of course,' agreed Miss Dammers, 'it's perfect.'
'Thank you,' murmured Mr. Bradley. 'Then you'll be able to understand just how disconcerting that discovery of mine was. Because if there was anything in that point at all, anybody who had in his or her possession some old notepaper of Mason's, with slightly discoloured edges, immediately became suspect.'
' Hr - r - r - r - mph!' Sir Charles cleared his throat forcibly by way of comment. The implication was obvious. Gentlemen don't suspect their own sisters.
'Dear, dear,' clucked Mr. Chitterwick, more humanly.
Mr. Bradley went on to pile up the agony. 'And there was another thing, which I could not overlook. My sister before she went in for her training as a secretary, had played with the idea of becoming a hospital nurse. She went through a short course in nursing as a young girl, and was always thoroughly interested in it. She would read not only books on nursing itself, but medical books too. Several times,' said Mr. Bradley solemnly, 'I've seen her studying my own copy of Taylor, apparently quite absorbed in it.'
He paused again, but this time nobody commented. The general feeling was that this was getting really too much of a good thing.
'Well, I went home and thought it over. Of course it seemed absurd to put my own sister on the list of suspects, and at the very head of it too. One doesn't connect one's own circle with the idea of murder. The two things don't mix at all. Yet I couldn't fail to realise that if it had been anybody else in question but my sister I should be feeling quite jubilant over the prospect of solving the case. But as things were, what was I to do?
'In the end,' said Mr. Bradley smugly, 'I did what I thought my duty and faced the situation. I went back to my sister's house the next day and asked her squarely whether she had ever had any kind of relations with Sir Eustace Pennefather, and if so what. She looked at me blankly and said that up till the time of the murder she had never heard of the man. I believed her. I asked her if she could remember what she had been doing on the evening before the murder. She looked at me still more blankly and said that she had been in Manchester with her husband at that time, they had stayed at the Peacock Hotel, and in the evening had been to a cinema where they had seen a film called, so far as she could recall. Fires of Fate. Again I believed her.
'As a matter of routine precaution however I checked her statements later and found them perfectly correct; for the time of the posting of the parcel she had an unshakable alibi. I felt more relieved than I can say.' Mr. Bradley spoke in a low voice, with pathos and restraint, but Roger caught his eye as he looked up and there was a mocking glint in it which made the President feel vaguely uneasy. The trouble with Mr. Bradley was that one never quite knew with him.
'Having drawn a blank with my first ticket, then, I tabulated the conclusions I'd formed to date and set about considering the other points in the case.
'It then struck me that the Chief Inspector from Scotland Yard had been somewhat reticent about the evidence that night he addressed us. So I rang him up and asked him a few questions that had occurred to me. From him I learnt that the typewriter was a Hamilton No. 4, that is, the ordinary Hamilton model; that the hand - printed address on the cover was written with a fountain - pen, almost certainly an Onyx fitted with a medium - broad nib; that the ink was Halfield's Fountain - Pen Ink; and that there was nothing to be learned from the
