THE MURDER OF ROGER ACKROYD
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 any one 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."
