"She [Mabel Manderson] uttered a little laugh of impatience. 'So you think he has been talking me round. No, that is not so. I am merely sure he did not do it. Ah! I see you think that absurd. But see how unreasonable you are, Mr Trent! Just now you were explaining to me quite sincerely that it was foolishness in you to have a certain suspicion of me after seeing me and being in my atmosphere, as you said.' Trent started in his chair. She glanced at him and went on: 'Now, I and my atmosphere are much obliged to you, but we must stand up for the rights of other atmospheres. I know a great deal more about Mr Marlowe's atmosphere than you know about mine even now. I saw him constantly for several years. I don't pretend to know all about him; but I do know that he is incapable of a crime of bloodshed. The idea of his planning a murder is as unthinkable to me as the idea of your picking a poor woman's pocket, Mr Trent.'"
