Japp stopped, and Poirot nodded, and said with the relish of the specialist: ‘Une belle affaire! And there was no clue as to the perpetrator of the deed? But how should there be!’
‘Well,’ continued the inspector, ‘you know the rest. The tragedy was a double one. Next day there were headlines in all the papers, and a brief statement to the effect that Miss Courtenay, the popular actress, had been discovered dead in her bed, and that her death was due to an overdose of cocaine. Now, was it accident or suicide? Her maid, who was called upon to give evidence, admitted that Miss Courtenay was a confirmed taker of the drug, and a verdict of accidental death was returned. Nevertheless we can’t leave the possibility of suicide out of account. Her death is particularly unfortunate, since it leaves us no clue now to the cause of the quarrel the preceding night. By the way, a small enamel box was found on the dead man. It had Coco written across it in diamonds, and was half full of cocaine. It was identified by Miss Courtenay’s maid as belonging to her mistress, who nearly always carried it about with her, since it contained her supply of the drug to which she was fast becoming a slave.’
‘Was Lord Cronshaw himself addicted to the drug?’
‘Very far from it. He held unusually strong views on the subject of dope.’
Poirot nodded thoughtfully.
‘But since the box was in his possession, he knew that Miss Courtenay took it. Suggestive, that, is it not, my good Japp?’
‘Ah!’ said Japp rather vaguely.
I smiled.
‘Well,’ said Japp, ‘that’s the case. What do you think of it?’
‘You found no clue of any kind that has not been reported?’
‘Yes, there was this.’ Japp took a small object from his pocket and handed it over to Poirot. It was a small pompon of emerald green silk, with some ragged threads hanging from it, as though it had been wrenched violently away.
‘We found it in the dead man’s hand, which was tightly clenched over it,’ explained the inspector.
Poirot handed it back without any comment and asked: ‘Had Lord Cronshaw any enemies?’
‘None that anyone knows of. He seemed a popular young fellow.’
‘Who benefits by his death?’
‘His uncle, the Honourable Eustace Beltane, comes into the title and estates. There are one or two suspicious facts against him. Several people declare that they heard a violent altercation going on in the little supper-room, and that Eustace Beltane was one of the disputants. You see, the table-knife being snatched up off the table would fit in with the murder being done in the heat of a quarrel.’
‘What does Mr Beltane say about the matter?’
‘Declares one of the waiters was the worse for liquor, and that he was giving him a dressing down. Also that it was nearer to one than half past. You see, Captain Digby’s evidence fixes the time pretty accurately. Only about ten minutes elapsed between his speaking to Cronshaw and the finding of the body.’
‘And in any case I suppose Mr Beltane, as Punchinello, was wearing a hump and a ruffle?’
‘I don’t know the exact details of the costumes,’ said Japp, looking curiously at Poirot. ‘And anyway, I don’t quite see what that has got to do with it?’
‘No?’ There was a hint of mockery in Poirot’s smile. He continued quietly, his eyes shining with the green light I had learned to recognize so well: ‘There was a curtain in this little supper-room, was there not?’
‘Yes, but—’
‘With a space behind it sufficient to conceal a man?’
‘Yes—in fact, there’s a small recess, but how you knew about it—you haven’t been to the place, have you, Monsieur Poirot?’
‘No, my good Japp, I supplied the curtain from my brain. Without it, the drama is not reasonable. And always one must be reasonable. But tell me, did they not send for a doctor?’
‘At once, of course. But there was nothing to be done. Death must have been instantaneous.’
Poirot nodded rather impatiently.
‘Yes, yes, I understand. This doctor, now, he gave evidence at the inquest?’
‘Yes.’
