The amount of missing girls I've had to trace and their family and their friends always say the same thing. 'She was a bright and affectionate disposition and had no men friends'. That's never true. It's unnatural. Girls ought to have men friends. If not, then there's something wrong about them.
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.
But I know human nature, my friend, and I tell you that, suddenly confronted with the possibility of being tried for murder, the most innocent person will lose his head and do the most absurd things.
