“You shall hear all about it tomorrow.”

“Because wherever you’re going, I’m coming too.”

“But mademoiselle—”

“I’m coming too, I tell you.”

Poirot realized that it was futile to argue further. He gave in.

“Come then, mademoiselle. But it will not be amusing. In all probability nothing will happen.”

The girl made no reply.

Twenty minutes later we set forth. It was quite dark now, a close, oppressive evening. Poirot led the way out of the town in the direction of the Villa Geneviève. But when he reached the Villa Marguerite he paused.

“I should like to assure myself that all goes well with Jack Renauld. Come with me, Hastings. Mademoiselle will perhaps remain outside. Madame Daubreuil might say something which would wound her.”

We unlatched the gate, and walked up the path. As we went round to the side of the house, I drew Poirot’s attention to a window on the first floor. Thrown sharply on the blind was the profile of Marthe Daubreuil.
