It seems plausible that Boswell will be coming after Audrey, so the group retires to her house and considers the possibility of laying a trap for him. Around 9pm, Inspector Jameson arrives, having seen Audrey’s name on the list of deposit-box holders and wondering just what would attract such unusual attention. She tells him some of what’s going on, in particular that the box contained papers related to an ongoing enquiry; he confirms that the boxes are quite substantial, and a large constable was able to carry just six of them, while twenty have gone missing. He leaves a man on watch outside Audrey’s house, which perhaps isn’t entirely welcome, but nobody else turns up during the night.
