“I am at your service, Lady Willard. You wished to consult me?”

“You are, I am aware, a detective, but it is not only as a detective that I wish to consult you. You are a man of original views, I know, you have imagination, experience of the world; tell me, Monsieur Poirot, what are your views on the supernatural?”

“Let us not misunderstand each other, Lady Willard. It is not a general question that you are asking me there. It has a personal application, has it not? You are referring obliquely to the death of your late husband?”

“That is so,” she admitted.

“You want me to investigate the circumstances of his death?”
