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 reprdsentatbn, and if so, you understand, the costumes would be important.’
Mrs Davidson still looked a bit doubtful.
‘I’ve heard of reconstructing a crime, of course,’ she said. ‘But ,I didn’t know you were so particular about details. But I’ll fetch the dress now.’
She left the room and returned almost immediately with a dainty wisp of white satin and green. Poirot took it from her and examined it, handing it back with a bow.
‘Merci, madameI see you have had the misfortune to lose one of your green pompons, the one on the shoulder here.’
‘Yes, it got torn off at the ball. I picked it up and gave it to poor
Lord Cronshaw to keep for me.’ ‘That was after supper?’ ‘Yes.’
‘Not long before the tragedy, perhaps?’
A faint look of alarm came into Mrs Davidson’s pale eyes, and she replied quickly: ‘Oh no – long before that. Quite soon after supper, in fact.’
‘I see. Well, that is all. I will not derange you further. Bonjour, ttladame.’ ‘Well,’ I said, as we emerged from the building, ‘that explains the mystery of the green pompon.’ ‘I wonder.’ ‘Why, what do you mean?’ ‘You saw me examine the dress, Hastings?’ ‘Yes?’ ‘Eh bien, the pompon that was missing had not been wrenched off, as the lady said. On the contrary, it had been cut off, my friend, cut off with scissors. The threads were all quite even.’ ‘Dear reel’ I exclaimed. ‘This becomes more and more involved.’ ‘On the contrary,’ replied Poirot placidly, ‘it becomes more and more simple.’ ‘Poirot,’ I cried, ‘one day I shall murder you! Your habit of finding everything perfectly simple is aggravating to the last degree!’ ‘But when I explain, rnon ami, is it not always perfectly simple?’ ‘Yes; that is the annoying part of it! I feel then that I could have done it myself.’ ‘And so you could, Hastings, so you could. If you would but take the trouble of arranging your ideas! Without method – ‘ ‘Yes, yes,’ I said hastily, for I knew Poirot’s eloquence when started on his favourite theme only too well. ‘Tell me, what do we do next? Are you really going to reconstruct the crime?’ ‘Hardly that. Shall we say that the drama is over, but that I propose to add a – harlequinade?’
The following Tuesday was fixed upon by Poirot as the day for this mysterious performance. The preparations greatly intrigued me. A white screen was erected at one side of the room, flanked by heavy curtains at either side. A man with some lighting apparatus arrived next, and finally a group of members of the theatrical profession, who disappeared into Poirot’s bedroom, which had been rigged up as a temporary dressing-room.
Shortly before eight, Japp arrived, in no very cheerful mood. I gathered that the official detective hardly approved of Poirot’s plan.
‘Bit melodramatic, like all his ideas. But there, it can do no harm, and as he says, it might save us a good bit of trouble. He’a been very smart over the case. I was on the same scent myself, of course – ‘ I felt instinctively that Japp was straining the truth here – ‘but there, I promised to let him play the thing out his own way. Ahl Here is the crowd.’
His Lordship arrived first, escorting Mrs Mallaby, whom I had not as yet seen. She was a pretty, dark-haired woman, and appeared perceptibly nervous. The Davidsons followed. Chris Davidson also I saw for the first time. He was handsome enough in a rather obvious style, tall and dark, with the easy grace of the actor.
