"Oh dear," Keene murmurs, with a professional equivocation that suggests she would not be surprised to find it so, but nor yet does she necessarily accept that it is. This appears to be all she has to say for now, and the Inspector recognises the sticky sort of silence, the kind you’re supposed to fall into, and wonders whether she should. She feels no urgent need to fill it, but that might indicate to Keene an unhealthy disconnection from normative behaviour. On the other hand, Keene will be using the Witness to read her—damn Smith’s kinesic assistant, with several Welfare Office extensions, no doubt—and she will know that Neith is thinking rather than feeling right now, so an attempt to counterfeit emotional response will definitely appear deceptive. She shrugs.
