‘But Parker is the most likely. It is in my mind to try a little experiment with Parker. How say you, my friend, will you accompany me to Fernly?’ I acquiesced, and we set out at once. Poirot asked to see Miss Ackroyd, and presently Flora came to us.
‘Mademoiselle Flora,’ said Poirot, ‘I have to confide in you a little secret. I am not yet satisfied of the innocence of Parker. I propose to make a little experiment with your assistance. I want to reconstruct some of his actions on that night. But we must think of something to tell him – ah! I have it. I wish to satisfy myself as to whether voices in the little lobby could have been heard outside on the terrace.
Now, ring for Parker, if you will be so good.’ I did so, and presently the butler appeared, suave as ever.
‘You rang, sir?’ ‘Yes, my good Parker. I have in mind a little experiment.
I have placed Major Blunt on the terrace outside the study window. I want to see if anyone there could have heard the voices of Miss Ackroyd and yourself in the lobby that night.
I want to enact that little scene over again. Perhaps you would fetch the tray or whatever it was you were carrying?’ Parker vanished, and we repaired to the lobby outside the study door. Presently we heard a chink in the outer hall, and Parker appeared in the doorway carrying a tray with a siphon, a decanter of whisky, and two glasses on it.
‘One moment,’ cried Poirot, raising his hand and seemingly very excited. ‘We must have everything in order.
Just as it occurred. It is a little method of mine.’ ‘A foreign custom, sir,’ said Parker. ‘Reconstruction of the crime they call it, do they not?’ He was quite imperturbable as he stood there politely waiting on Poirot’s orders.
‘Ah! he knows something, the good Parker,’ cried Poirot.
‘He has read of these things. Now, I beg you, let us have everything of the most exact. You came from the outer hall – so. Mademoiselle was – where?’ ‘Here,’ said Flora, taking up her stand just outside the study door.
‘Quite right, sir,’ said Parker.
‘I had just closed the door,’ continued Flora.
‘Yes, miss,’ agreed Parker. ‘Your hand was still on the handle as it is now.’ ‘Then allez,’ said Poirot. ‘Play me the little comedy.’ Flora stood with her hand on the door handle, and Parker came stepping through the door from the hall, bearing the tray.
He stopped just inside the door. Flora spoke.
‘Oh! Parker. Mr Ackroyd doesn’t want to be disturbed again tonight.’ ‘Is that right?’ she added in an undertone.
‘To the best of my recollection, Miss Flora,’ said Parker, ‘but I fancy you used the word evening instead of night.’ Then, raising his voice in a somewhat theatrical fashion: ‘Very good, miss. Shall I lock up as usual?’ ‘Yes, please.’ Parker retired through the door. Flora followed him, and started to ascend the main staircase.
‘Is that enough?’ she asked over her shoulder.
‘Admirable,’ declared the little man, rubbing his hands.
‘By the way, Parker, are you sure there were two glasses on the tray that evening? Who was the second one for?’ ‘I always bring two glasses, sir,’ said Parker. ‘Is there anything further?’ ‘Nothing. I thank you.’ Parker withdrew, dignified to the last.
Poirot stood in the middle of the hall frowning. Flora came down and joined us.
‘Has your experiment been successful?’ she asked. ‘I don’t quite understand, you know -‘ Poirot smiled admiringly at her.
‘It is not necessary that you should,’ he said. ‘But tell me, were there indeed two glasses on Parker’s tray that night?’ Flora wrinkled her brows a minute.
‘I really can’t remember,’ she said. ‘I think there were. Is – is that the object of your experiment?’ Poirot took her hand and patted it.
‘Put it this way,’ he said. ‘I am always interested to see if people will speak the truth.’ ‘And did Parker speak the truth?’ ‘I rather think he did,’ said Poirot thoughtfully.
A few minutes later saw us retracing our steps to the village.
