Two steps lead down into a small anteroom. The way is barred by a second door, no less formidable than the first. Daniel steps forward and down in to this space, takes out his key, and after a few moments’ trial and error, works out which lock it is meant to open. That achieved, he ascends back to cloister level, for there is only room there for one Key-holder and one lanthorn-man. Presently all three inner-door locks have been removed, and brought out into the light, and the hasp is undone. Eyes turn to Daniel again. He goes down in there and puts his shoulder to the door and shoves. It swings halfway open and stops resolutely, as he knew it would. The vault beyond is twice as ancient as the Chapter House. It was rifled during some 13th-Century disturbance—for this is where the Abbey stores its plate and other treasures—and so they installed a stone kerb on the floor so that the door could not be swung fully a-gape, and any future looters would have to ferry the goods out one bauble at a time, as opposed to by the chest-load.
