THE K ING'S H EAD T AVERN was dark, but it was not closed. When Daniel entered he saw patches of glowing green light here and there – pooled on tabletops and smeared on walls – and heard Persons of Quality speaking in hushed voices punctuated by outbreaks of riotous giggling. But the glow faded, and then serving-wenches scurried out with rush-lights and re-lit all of the lamps, and finally Daniel could see Pepys and Wilkins and Comstock, and the Duke of Gunfleet, and Sir Christopher Wren, and Sir Winston Churchill, and – at the best table – the Earl of Upnor, dressed in what amounted to a three-dimensional Persian carpet, trimmed with fur and studded with globs of colored glass, or perhaps they were precious gems.
