Dawn was beginning to glaze the rooftops and I was feeling the lack of a good night’s sleep. Behind me, at his machine, Liam tapped his way through yet another stream of film from yet another camera, as we tried to find out what time Sil had left the Records Office. If we knew how long he’d been there we might have some clue as to what he’d been doing. ‘Nope. Still no sign and I’m at half an hour after they closed.’ ‘Could he have come out another way?’ I turned to see a shrug. ‘Maybe, but everyone else has used the front door, even the staff. And I’ve checked all the other cameras around, doesn’t look like he snuck out of a fire escape either. And besides’—he stood up now—‘wouldn’t that line us up a whole new set of questions?’ I leaned the back of my head against the office wall. The plasterboard rocked slightly under my weight and I briefly wondered whether we should take up Zan on his office share suggestion.
