"The Lord only knows. There's one thing, Inglethorp himself
won't be too keen on meeting her."

"You've got the keys still, haven't you, Poirot?" I asked, as we
reached the door of the locked room.

Taking the keys from Poirot, John unlocked it, and we all passed
in. The lawyer went straight to the desk, and John followed him.

"My mother kept most of her important papers in this
despatch-case, I believe," he said.

Poirot drew out the small bunch of keys.

"Permit me. I locked it, out of precaution, this morning."

"But it's not locked now."

"Impossible!"

"See." And John lifted the lid as he spoke.

"Milles tonnerres!" cried Poirot, dumfounded. "And I--who have
both the keys in my pocket!" He flung himself upon the case.
Suddenly he stiffened. "En voila une affaire! This lock has been
forced."

"What?"

Poirot laid down the case again.
