Agatha Christie,
The Big Four
(1927)
“ What do you want of me, M. Poirot? You are a terrible man. You hunted me from London. Now, I suppose, you will tell our wonderful Madame Olivier about me, and hunt me from Paris? We poor Russians, we must live, you know.""It is more serious than that, madame," said Poirot, watching her. "I propose to enter the villa next door, and release M. Halliday, if he is still alive. I know everything, you see." ”
