Last night, perhaps, some messenger, despatched from London by Bolingbroke, had galloped into the fort at Sheerness and presented this captain with an order to scour the estuary for such-and-such a sloop, and to capture the foreign spies aboard it. Which might have sounded straightforward enough at the time. Bolingbroke’s seal dangling from the document, the exhausted post-horse blowing outside, the spattered and red-eyed messenger, the urgent missive in the dead of night: just the sort of thing ambitious naval officers prayed for. He had done his duty well this morning. But now something had gone awry: he had been presented with an opportunity to think. The royal arms rippling from the mast-head of the grounded sloop gave him much to think about, and much incentive to think carefully.
