You are the patient one, Mademoiselle,' said Poirot to Miss Debenham. She shrugged her shoulders slightly. 'What else can one do?' You are a philosopher, Mademoiselle.' That implies a detached attitude. I think my attitude is more selfish. I have learned to save myself useless emotion.

You cannot mix up sentiment and reason.

One place is very like another.

Things never come when they are expected.

Nurses - nurses, you'm all the same. Full of cheerfulness over other people's troubles.

Words are such uncertain things, they so often sound well but mean the opposite of what one thinks they do.

To all those who lead monotonous lives in the hope that they may experience at second hand the delights and dangers of adventure. [author's dedication]
