underneath. Ormerin helped him. The throne was roughly knocked up for me in the village and the boards have warped apart. The blade is much narrower at the tip than at the hilt. The tip went through easily, but he hammered at the hilt to force it right up. The boards gripped the wider end. You will see all that when you look at it.”
    “Yes.” Alleyn made a note in his book and waited.
    “The drape was arranged to hide the knife and it all looked quite convincing. Sonia was — she was quite — frightened. Hatchett pulled the knife out — it needed some doing — and we put everything straight again.”
    “What happened to the knife?”
    “Let me see. I think Hatchett put it away.”
    “From a practical point of view, how could you be sure that the knife would come through at exactly the right place to do what it has done?”
    “The position of the figure is chalked on the floor. When she took her pose, Sonia fitted her right hip and leg into the chalk-marks, and then slid down until the whole of her right side was on the floor. One of the students would move her until she was inside the marks. Then she let her torso go over until her left shoulder touched the floor. The left hip was off the ground. I could draw it for you.”
    Alleyn opened his note-book at a clean page and handed it to her with his pencil. Troy swept a dozen lines down and gave it back to him.
    “Wonderful!” said Alleyn, “to be able to do that — so easily.”
    “I’m not likely to forget that pose,” said Troy dryly.
    “What about the drape? Didn’t that cover the chalk-marks?”
    “Only in places. It fell from a suspension-point on the cushion to the floor. As she went down, she carried it with her. The accidental folds that came that way were more interesting than any laboured arrangement. When the students made their experiment they found the place where the heart would be, quite easily, inside the trace on the floor. The crack passed through this point. Hatchett put a pencil through the crack and they marked the position on the under-side of the throne.”
    “Is there any possibility that they repeated this performance for some reason on Friday and forgot to withdraw the dagger?”
    “I thought of that at once, naturally. I asked them. I begged them to tell me.” Troy moved her long hands restlessly. “Anything,” she said, “anything rather than the thought of one of them deliberately — there’s no reason. I–I can’t bear to think of it. As if a beastly unclean thing was in one of their minds, behind all of us. And then, suddenly, crawled out and did this.”
    He heard her draw in her breath sharply. She turned her head away.
    Alleyn swore softly.
    “Oh, don’t pay any attention to me,” said Troy impatiently. “I’m all right. About Friday. We had the morning class as usual from ten o’clock to twelve-thirty, with that pose. We all lunched at one. Then we went up to London. The private view of the Phoenix Group Show was on Friday night, and several of us had things in it. Valmai Seacliff and Basil Pilgrim, who are engaged to be married, left in his two-seater immediately after lunch. Neither of them was going to the private view. They were going to his people’s place, to break the engagement news, I imagine. Katti Bostock and I left in my car at about half-past two. Hatchett, Phillida Lee and Ormerin caught the three o’clock bus. Malmsley wanted to do some work, so he stayed behind until six, went up in the six-fifteen bus and joined us later at the show. I believe Phillida Lee and Hatchett had a meal together and went to a show. She took him to her aunt’s house in London for the week-end, I fancy.”
    “And the model?”
    “Caught the two-thirty bus. I don’t know where she went or what she did. She came back with Malmsley, Ormerin, Katti Bostock, Hatchett and Phillida Lee by yesterday evening’s bus.”
    “When Friday’s class broke up, did you all leave the studio together and come up to the
