Neith rolls her eyes and tells Keene she can’t come in, at which Keene, of course, does. The whole moment is typical of her: first to get Neith to say that she is all right, and know it for the truth, and then to assert the soft prerogative of entry that her role gives her anyway, but so smoothly as to feel like a friend and not a colleague. WWO Keene is as good at her job as DI Neith is at hers. But she is also—as a person—perplexingly opaque. The Inspector—as an officer of the Witness—dislikes opacity.
