“Miss Cynthia has a green evening dress.”
“Light or dark green?”
“A light green, sir; a sort of chiffon, they call it.”
“Ah, that is not what I want. And nobody else has anything green?”
“No, sir—not that I know of.”
Poirot’s face did not betray a trace of whether he was disappointed or otherwise. He merely remarked:
“Good, we will leave that and pass on. Have you any reason to believe that your mistress was likely to take a sleeping powder last night?”
“Not last night, sir, I know she didn’t.”
