“This is the message.” I dropped my voice still lower. “ ‘Find the extra coffee-cup, and you can rest in peace.’ ”
“What on earth does he mean?” Lawrence stared at me in quite unaffected astonishment.
“Don’t you know?”
“Not in the least. Do you?”
I was compelled to shake my head.
“What extra coffee-cup?”
“I don’t know.”
“He’d better ask Dorcas, or one of the maids, if he wants to know about coffee-cups. It’s their business, not mine. I don’t know anything about the coffee-cups, except that we’ve got some that are never used, which are a perfect dream! Old Worcester. You’re not a connoisseur, are you, Hastings?”
I shook my head.
“You miss a lot. A really perfect bit of old china—it’s pure delight to handle it, or even to look at it.”
“Well, what am I to tell Poirot?”
“Tell him I don’t know what he’s talking about. It’s double Dutch to me.”
“All right.”
I was moving off towards the house again when he suddenly called me back.
