HANOVER WAS LANDLOCKED. Its greatest body of water was a three-mile-wide puddle. The rich might invest in, the rash might sail on, proper ships; but they had to travel abroad to Bremerhaven first. For most Hanoverians, the preferred way of getting to the other side of a body of water was to wait for it to freeze, then sprint across. Sophia, the sloop that Caroline and Johann had boarded in the dead of night off the Isle of Dogs, was technically a Hanoverian vessel, in that she carried impressive-looking documents asserting that she was. But the crew consisted mostly of boys from Friesland, the skipper was an Antwerp Protestant named Ursel, and the lads who had muscled the oars of the longboat last night had been hired, along with the boat, from a Danish whaler that was having her hull scraped in Rotherhithe. Those Danes were now waking up with sore backs in East London. Much water, some fresh and some brackish, had passed beneath Sophia ’s keel in the meantime.
