The Alphabet Murders

Hastings:
Where have you been? What have you been doing?

Hercule Poirot:
Arranging a little extra insurance my friend.

Hastings:
Oh really? Personally I always feel perfectly safe with British railways. Mind you its very different in France, isn't it?

Hercule Poirot:
I wouldn't know. I am not French, I am Belgian.

Hastings:
Well it's the same thing, you both eat horsemeat.
