While the light lasts

Thus Johnnie in the early hours of the following morning. M. Poirot sat up in bed. He wore a night-cap. The contrast between the dignity of his countenance and the rakish tilt of the nightcap was certainly droll; but its effect on Johnnie seemed disproportionate. But for his words, one might have fancied that the boy was violently amused about something. Curious sounds came from outside the door, too, suggesting soda-water syphons in difficulty.

'Come down at once, please,' continued Johnnie, his voice shaking slightly. 'Someone's been killed.' He turned away.

'Aha, that is serious!' said M. Poirot.

He arose, and, without unduly hurrying himself, made a partial toilet. Then he followed Johnnie down the stairs. The house-party was clustered round the door into the garden. Their countenances all expressed intense emotion. At sight of him Eric was seized with a violent choking fit.

Jean came forward and laid her hand on M. Poirot's arm.

'Look!' she said, and pointed dramatically through the open door.

'Mon Dieu!' ejaculated M. Poirot. 'It is like a scene on the stage.'

His remark was not inapposite. More snow had fallen during the night, the world looked white and ghostly in the faint light of the early dawn. The expanse of white lay unbroken save for what looked like on splash of vivid scarlet.

Nancy Cardell lay motionless on the snow. She was clad in scarlet silk pyjamas, her small feet were bare, her arms were spread wide. Her head was turned aside and hidden by the mass of her clustering black hair. Deadly still she lay, and from her left side rose up the hilt of a dagger, whilst on the snow there was an ever-widening patch of crimson.

Poirot went out into the snow. He did not go to where the girl's body lay, but kept to the path. Two tracks of foot-marks, a man's and a woman's, led to where the tragedy had occurred. The man's footprints went away in the opposite direction alone. Poirot stood on the path, stroking his chin reflectively.

Suddenly Oscar Levering burst out of the house.

'Good God!' he cried. 'What's this?'

His excitement was a contrast to the other's calm.

'It looks,' said M. Poirot thoughtfully, 'like murder.'

Eric had another violent attack of coughing.

'But we must do something,' cried the other. 'What shall we do?'

'There is only one thing to be done,' said M. Poirot. 'Send for the police.'

'Oh!' said everybody at once.

M. Poirot looked inquiringly at them.

'Certainly,' he said. 'It is the only thing to be done. Who will go?'

There was a pause, then Johnnie came forward.

'Rag's over,' he declared. 'I say, M. Poirot, I hope you won't be too mad with us. It's all a joke, you know - got up between us - just to pull your leg. Nancy's only shamming.'

M. Poirot regarded him without visible emotion, save that his eyes twinkled a moment.

'You mock yourselves at me, is that it?' he inquired placidly.

'I say, I'm awfully sorry really. We shouldn't have done it. Beastly bad taste. I apologize, I really do.'

'You need not apologize,' said the other in a peculiar voice.

Johnnie turned.

'I say, Nancy, get up!' he cried. 'Don't lie there all day.'

But the figure on the ground did not move.

'Get up,' cried Johnnie again.

Still Nancy did not move, and suddenly a feeling of nameless dread came over the boy. He turned to Poirot.

'What - what's the matter? Why doesn't she get up?'

'Come with me,' said Poirot curtly.

He strode over the snow. He had waved the others back, and he was careful not to infringe on the other footmarks. The boy followed him, frightened and unbelieving. Poirot knelt down by the girl, then he signed to Johnnie.

'Feel her hand and pulse.'

Wondering, the boy bent down, then started back with a cry. The hand and arm were stiff and cold, and no vestige of a pulse was to be found.

'She's dead!' he gasped. 'But how? Why?'

M. Poirot passed over the first part of the question.

'Why?' he said musingly. 'I wonder.' Then, suddenly leaning across the dead girl's body, he unclasped her other hand, which was tightly clenched over something. Both he and the boy uttered an exclamation. In the palm of Nancy's hand was a red stone that winked and flashed forth fire.

'Aha!' cried M. Poirot. Swift as a flash his hand flew to his pocket, and came away empty.

'The cracker ruby,' said Johnnie wonderingly. Then, as his companion bent to examine the dagger, and the stained snow, he cried out: 'Surely it can't be blood, M. Poirot. It's paint. It's only paint.'

Poirot straightened himself.

'Yes,' he said quietly. 'You are right. It's only paint.'

'Then how -' The boy broke off. Poirot finished the sentence for him.

'How was she killed? That we must find out. Did she eat or drink anything this morning?'

He was retracing his steps to the path where the others waited as he spoke. Johnnie was close behind him.

'She had a cup of tea,' said the boy. 'Mr Levering made it for her. He's got a spirit-lamp in his room.'

Johnnie's voice was loud and clear. Levering heard the words.
