Poirot nodded rather impatiently.
‘Yes, yes, I understand. This doctor, now, he gave evidence at the inquest?’
‘Yes.’
‘Did he say nothing of any unusual symptom—was there nothing about the appearance of the body which struck him as being abnormal?’
Japp stared hard at the little man.
‘Yes, Monsieur Poirot. I don’t know what you’re getting at, but he did mention that there was a tension and stiffness about the limbs which he was quite at a loss to account for.’
‘Aha!’ said Poirot. ‘Aha! Mon Dieu! Japp, that gives one to think, does it not?’
I saw that it had certainly not given Japp to think.
‘If you’re thinking of poison, monsieur, who on earth would poison a man first and then stick a knife into him?’
‘In truth that would be ridiculous,’ agreed Poirot placidly.
‘Now is there anything you want to see, monsieur? If you’d like to examine the room where the body was found—’
Poirot waved his hand.
‘Not in the least. You have told me the only thing that interests me—Lord Cronshaw’s views on the subject of drug taking.’
‘Then there’s nothing you want to see?’
‘Just one thing.’
‘What is that?’
‘The set of china figures from which the costumes were copied.’
Japp stared.
‘Well, you’re a funny one!’
‘You can manage that for me?’
‘Come round to Berkeley Square now if you like. Mr Beltane—or His Lordship, as I should say now—won’t object.’

We set off at once in a taxi. The new Lord Cronshaw was not at home, but at Japp’s request we were shown into the ‘china room’, where the gems of the collection were kept. Japp looked round him rather helplessly.
‘I don’t see how you’ll ever find the ones you want, monsieur.’
But Poirot had already drawn a chair in front of the mantelpiece and was hopping up upon it like a nimble robin. Above the mirror, on a small shelf to themselves, stood six china figures. Poirot examined them minutely, making a few comments to us as he did so.
‘Les voilà! The old Italian Comedy. Three pairs! Harlequin and Columbine, Pierrot and Pierrette—very dainty in white and green—and Punchinello and Pulcinella in mauve and yellow. Very elaborate, the costume of Punchinello—ruffles and frills, a hump, a high hat. Yes, as I thought, very elaborate.’
He replaced the figures carefully, and jumped down.
Japp looked unsatisfied, but as Poirot had clearly no intention of explaining anything, the detective put the best face he could upon the matter. As we were preparing to leave, the master of the house came in, and Japp performed the necessary introductions.
The sixth Viscount Cronshaw was a man of about fifty, suave in manner, with a handsome, dissolute face. Evidently an elderly roué, with the languid manner of a poseur. I took an instant dislike to him. He greeted us graciously enough, declaring he had heard great accounts of Poirot’s skill, and placing himself at our disposal in every way.
‘The police are doing all they can, I know,’ Poirot said.
‘But I much fear the mystery of my nephew’s death will never be cleared up. The whole thing seems utterly mysterious.’
Poirot was watching him keenly. ‘Your nephew had no enemies that you know of?’
‘None whatever. I am sure of that.’ He paused, and then went on: ‘If there are any questions you would like to ask—’
‘Only one.’ Poirot’s voice was serious. ‘The costumes—they were reproduced exactly from your figurines?’
‘To the smallest detail.’
‘Thank you, milor’. That is all I wanted to be sure of. I wish you good day.’
‘And what next?’ inquired Japp as we hurried down the street. ‘I’ve got to report at the Yard, you know.’
‘Bien! I will not detain you. I have one other little matter to attend to, and then—’
‘Yes?’
‘The case will be complete.’
‘What? You don’t mean it! You know who killed Lord Cronshaw?’
‘Parfaitement.’
‘Who was it? Eustace Beltane?’
‘Ah, mon ami, you know my little weakness! Always I have a desire to keep the threads in my own hands up to the last minute. But have no fear. I will reveal all when the time comes. I want no credit—the affair shall be yours, on the condition that you permit me to play out the dénouement my own way.’
‘That’s fair enough,’ said Japp. ‘That is, if the dénouement ever comes! But I say, you are an oyster, aren’t you?’ Poirot smiled. ‘Well, so long. I’m off to the Yard.’
He strode off down the steet, and Poirot hailed a passing taxi.
‘Where are we going now?’ I asked in lively curiosity.
‘To Chelsea to see the Davidsons.’
He gave the address to the driver.
‘What do you think of the new Lord Cronshaw?’ I asked.
‘What says my good friend Hastings?’
‘I distrust him instinctively.’
‘You think he is the “wicked uncle” of the story-books, eh?’
‘Don’t you?’
‘Me, I think he was most amiable towards us,’ said Poirot noncommittally.
‘Because he had his reasons!’
Poirot looked at me, shook his head sadly, and murmured something that sounded like: ‘No method.’

The Davidsons lived on the third floor of a block of ‘mansion’ flats. Mr Davidson was out, we were told, but Mrs Davidson was at home. We were ushered into a long, low room with garish Oriental hangings. The air felt close and oppressive, and there was an overpowering fragrance of joss-sticks. Mrs Davidson came to us almost immediately, a small, fair creature whose fragility would have seemed pathetic and appealing had it not been for the rather shrewd and calculating gleam in her light blue eyes.
Poirot explained our connection with the case, and she shook her head sadly.
‘Poor Cronch—and poor Coco too! We were both so fond of her, and her death has been a terrible grief to us. What is it you want to ask me? Must I really go over all that dreadful evening again?’
‘Oh, madame, believe me, I would not harass your feelings unnecessarily. Indeed, Inspector Japp has told me all that is needful. I only wish to see the costume you wore at the ball that night.’
The lady looked somewhat surprised, and Poirot continued smoothly: ‘You comprehend, madame, that I work on the system of my country. There we always “reconstruct” the crime. It is possible that I may have an actual représentation, and if so, you understand, the costumes would be important.’
