Broody had been enthusiastic about the Visitors’ Book, always passing it round when there were guests present. ‘If nothing else, it’ll give you and Ollie something to read during the refit,’ he had said to Dagwood.The Visitor’s Book was, in its own way, as complete a record of the commission as the control-room log.
