By tacit consent, all mention of the tragedy was barred. We
conversed on the war, and other outside topics. But after the
cheese and biscuits had been handed round, and Dorcas had left
the room, Poirot suddenly leant forward to Mrs. Cavendish.
"Pardon me, madame, for recalling unpleasant memories, but I have
a little idea"--Poirot's "little ideas" were becoming a perfect
byword--"and would like to ask one or two questions."
"Of me? Certainly."
"You are too amiable, madame. What I want to ask is this: the
door leading into Mrs. Inglethorp's room from that of
Mademoiselle Cynthia, it was bolted, you say?"
"Certainly it was bolted," replied Mary Cavendish, rather
surprised. "I said so at the inquest."
"Bolted?"
"Yes." She looked perplexed.
"I mean," explained Poirot, "you are sure it was bolted, and not
merely locked?"
"Oh, I see what you mean. No, I don't know. I said bolted,
meaning that it was fastened, and I could not open it, but I
believe all the doors were found bolted on the inside."
"Still, as far as you are concerned, the door might equally well
have been locked?"
"Oh, yes."
"You yourself did not happen to notice, madame, when you entered
Mrs. Inglethorp's room, whether that door was bolted or not?"
"I--I believe it was."
"But you did not see it?"
"No. I--never looked."
"But I did," interrupted Lawrence suddenly. "I happened to
notice that it *WAS bolted."
"Ah, that settles it." And Poirot looked crestfallen.
