I specialize in murders of quiet, domestic interest.

The point is that one's got an instinct to live. One doesn't live because one's reason assents to living. People who, as we say, 'would be better dead' don't want to die! People who apparently have everything to live for just let themselves fade out of life because they haven't got the energy to fight.

I've always believed in writing without a collaborator, because where two people are writing the same book, each believes he gets all the worry and only half the royalties.

I'm sorry, but I do hate this differentiation between the sexes. The modern girl has a thoroughly businesslike attitude to life! That sort of thing. It's not a bit true! Some girls are businesslike and some aren't. Some men are sentimental and muddle-headed, others are clear-headed and logical. There are just different types of brains.

Any woman can fool a man if she wants to and if he's in love with her.

I think, myself, that one's memories represent those moments which, insignificant as they may seem, nevertheless represent the inner self and oneself as most really oneself.

Writers are diffident creatures -- they need encouragement.
