‘It was then seen that a thin triangular blade protruded vertically through the drape. It appeared to be the blade of some sort of dagger that had been driven through a crack in the dais from underneath. It has not been moved. It seems that later on, when Miss Troy arrived, she stopped anybody from touching the dais as soon as she saw what had occurred. On examining Gluck a wound was discovered in the back somewhere about the position of the fourth rib and about three inches to the left of the spine. There was an effusion of blood. The blade was stained with blood. Miss Bostock attempted to staunch the wound with a rag. At this point Miss Troy arrived, and immediately sent Mr Basil Pilgrim, another student, to ring up the doctor. Dr Ampthill arrived ten minutes later and found life was extinct. Miss Troy states that Gluck died a few minutes after she—Miss Troy—arrived at the studio. Gluck made no statement before she died.’

Mr Blackman closed his notebook, and laid it on the table.

‘That’s just from notes,’ he said modestly. ‘I haven’t got it down in a ship-shape report yet.’

‘It is sufficiently clear,’ said Alleyn. ‘You might have been giving it to a jury.’

An expression of solemn complacency setded down among the superintendent’s chins.

‘Well,’ he said, ‘we haven’t had a great deal of time. It’s a curious business. We’ve taken statements from all this crowd, except, of course, the man called Garcia. He’s gone, and we haven’t got a line on him. That looks a bit funny on the face of it, but it seems he said he’d be leaving for a hiking trip on Saturday morning, and is due to turn up at some place in London in about a week’s time. He left his luggage to be forwarded to this London address, and it had all gone when Miss Troy returned on Saturday about three o’clock. We’re trying to get on to the carrier that called for it, but haven’t got hold of anybody yet. It was all in the studio. It seems Garcia slept in the studio and had his gear there. I’ve got into touch with the police stations for fifty miles round and asked them to look out for this Garcia. Here’s the description of him: Height— about five foot nine; sallow complexion, dark eyes, very thin. Thick dark hair, rather long. Usually dressed in old grey flannel trousers and a raincoat. Does not wear a hat. Probably carrying a rucksack containing painting materials. It seems he does a bit of sketching as well as sculping. We got that in the course of the statements made by the rest of this crowd. Will you look at the statements before you see anybody?’

Alleyn thought for moment.

‘I’ll see Miss Troy first,’ he said. ‘I have met her before.’
