'Philip Garrod was turned out of the house with scant ceremony; but as a result of his rage Clode's own health took a decided turn for the worst. For the last month he had kept to his bed pretty continuously, and now there seemed every possibility of his being a bedridden invalid until such time as death should release him. Two days after Philip's departure I received an urgent summons and went hurriedly over. Clode was in bed and looked even to my layman's eye very ill indeed. He was gasping for breath.

'This is the end of me,' he said. 'I feel it. Don't argue with me, Petherick. But before I die I am going to do my duty by the one human being who has done more for me than anyone else in the world. I want to make a fresh will.'

'Certainly,' I said, 'if you will give me your instructions now I will draft out a will and send it to you.'

'That won't do,' he said. 'Why, man, I might not live through the night. I have written out what I want here,' he fumbled under the pillow, 'and you can tell me if it is right.'

'He produced a sheet of paper with a few words roughly scribbled on it in pencil. It was quite simple and clear. He left?5000 to each of his nieces and nephew, and the residue of his vast property outright to Eurydice Spragg 'in gratitude and admiration.'

'I didn't like it, but there it was. There was no question of unsound mind, the old man was as sane as anybody.

'He rang the bell for two of the servants. They came promptly. The housemaid, Emma Gaunt, was a tall middle-aged woman who had been in service there for many years and who had nursed Clode devotedly. With her came the cook, a fresh buxom young woman of thirty. Simon Clode glared at them both from under his bushy eyebrows.

'I want you to witness my will. Emma, get me my fountain pen.'

'Emma went over obediently to the desk.

'Not that left-hand drawer, girl,' said old Simon irritably. 'Don't you know it is in the right-hand one?'

'No, it is here, sir,' said Emma, producing it.

'Then you must have put it away wrong last time,' grumbled the old man. 'I can't stand things not being kept in their proper places.'

'Still grumbling he took the pen from her and copied his own rough draft, amended by me, onto a fresh piece of paper. Then he signed his name. Emma Gaunt and the cook, Lucy David, also signed. I folded the will up and put it into a long blue envelope.

'Just as the servants were turning to leave the room Clode lay back on the pillows with a gasp and a distorted face. I bent over him anxiously and Emma Gaunt came quickly back. However, the old man recovered and smiled weakly.

'It is all right, Petherick, don't be alarmed. At any rate I shall die easy now having done what I wanted to.'

'Emma Gaunt looked inquiringly at me as if to know whether she could leave the room. I nodded reassuringly and she went out - first stopping to pick up the blue envelope which I had let slip to the ground in my moment of anxiety. She handed it to me and I slipped it into my coat pocket and then she went out.

'You are annoyed, Petherick,' said Simon Clode. 'You are prejudiced, like everybody else.'

'It is not a question of prejudice,' I said. 'Mrs. Spragg may be all that she claims to be. I should see no objection to you leaving her a small legacy as a memento of gratitude; but I tell you frankly, Clode, that to disinherit your own flesh and blood in favour of a stranger is wrong.'

'With that I turned to depart. I had done what I could and made my protest.

'Mary Clode came out of the drawing-room and met me in the hall.

'You will have tea before you go, won't you? Come in here,' and she led me into the drawing-room.

'A fire was burning on the hearth and the room looked cosy and cheerful. She relieved me of my overcoat just as her brother, George, came into the room. He took it from her and laid it across a chair at the far end of the room, then he came back to the fireside where we drank tea. During the meal a question arose about some point concerning the estate. Simon Clode said he didn't want to be bothered with it and had left it to George to decide. George was rather nervous about trusting to his own judgment. At my suggestion, we adjourned to the study after tea and I looked over the papers in question. Mary Clode accompanied us.

'A quarter of an hour later I prepared to take my departure. Remembering that I had left my overcoat in the drawing-room, I went there to fetch it. The only occupant of the room was Mrs. Spragg, who was kneeling by the chair on which the overcoat lay. She seemed to be doing something rather unnecessary to the chair's slipcover. She rose with a very red face as we entered.

'That cover never did sit right,' she complained. 'My! I could make a better fit myself.'

'I took up my overcoat and put it on. As I did so I noticed that the envelope containing the will had fallen out of the pocket and was lying on the floor. I replaced it in my pocket, said good-bye, and took my departure.

'On arrival at my office, I will describe my next actions carefully. I removed my overcoat and took the will from the pocket. I had it in my hand and was standing by the table when my clerk came in. Somebody wished to speak to me on the telephone, and the extension to my desk was out of order. I accordingly accompanied him to the outer office and remained there for about five minutes engaged in conversation over the telephone.

'When I emerged I found my clerk waiting for me.

'Mr. Spragg has called to see you, sir. I showed him into your office.'

'I went there to find Mr. Spragg sitting by the table. He rose and greeted me in a somewhat unctuous manner, then proceeded to a long discursive speech. In the main it seemed to be an uneasy justification of himself and his wife. He was afraid people were saying, etc., etc. His wife had been known from her babyhood upwards for the pureness of her heart and her motives… and so on and so on. I was, I am afraid, rather curt with him. In the end I think he realised that his visit was not being a success and left somewhat abruptly. I then remembered that I had left the will lying on the table. I took it, sealed the envelope, and wrote on it and put it away in the safe.

'Now I come to the crux of my story. Two months later Mr. Simon Clode died. I will not go into long-winded discussions, I will just state the bare facts. When the sealed envelope containing the will was opened it was found to contain a sheet of blank paper.'

He paused, looking around the circle of interested faces. He smiled himself with a certain enjoyment.

'You appreciate the point, of course? For two months the sealed envelope had lain in my safe. It could not have been tampered with then. No, the time limit was a very short one. Between the moment the will was signed and my locking it away in the safe. Now who had had the opportunity, and to whose interest would it be to do so?

'I will recapitulate the vital points in a brief summary: The will was signed by Mr. Clode, placed by me in an envelope - so far so good. It was then put by me in my overcoat pocket. That overcoat was taken from me by Mary and handed by her to George, who was in full sight of me whilst handling the coat. During the time that I was in the study Mrs. Eurydice Spragg would have had plenty of time to extract the envelope from the coat pocket and read its contents and, as a matter of fact, finding the envelope on the ground and not in the pocket seemed to point to her having done so.

'But here we come to a curious point: she had the opportunity of substituting the blank paper, but no motive. The will was in her favour, and by substituting a blank piece of paper she despoiled herself of the heritage she had been so anxious to gain. The same applies to Mr. Spragg. He, too, had the opportunity. He was left alone with the document in question for some two or three minutes in my office. But again, it was not to his advantage to do so. So we are faced with the curious problem: the two people who had the opportunity of substituting a blank piece of paper had no motive for doing so, and the two people who had a motive had no opportunity. By the way, I would not exclude the housemaid, Emma Gaunt, from suspicion. She was devoted to her young master and mistress and detested the Spraggs. She would, I feel sure, have been quite equal to attempting the substitution if she had thought of it. But although she actually handled the envelope when she picked it up from the floor and handed it to me, she certainly had no opportunity of tampering with its contents and she could not have substituted another envelope by some sleight of hand (of which anyway she would not be capable) because the envelope in question was brought into the house by me and no one there would be likely to have a duplicate.'
