But then Daniel Waterhouse was right in the City of London – slightly confused, as some of the streets had been straightened and simplifed after the Fire. He pulled a fat gold egg from his pocket – one of Hooke's experimental watches, a failed stab at the Longitude Problem, adequate only for landlubbers. It told him that the Phosphorus Demo' was not quite finished at Whitehall, but that it was not too late to call on his in-laws. Daniel did not especially like to just call on people – seemed presumptuous to think they'd want to open the door and see him – but he knew that this was how men like Pepys got to become men like Pepys. So to the house of Ham.
