Waterhouse had been collected from the castle in unseemly haste. Dusk is now falling like a lead curtain, and wolf packs hunt at night. He is on the bridge of a corvette, a tiny escort ship that, in any kind of chop, has the exact hydrodynamics of an empty oil drum. If he stays down below he’ll never stop vomiting, and so he stands abovedecks, feet braced wide, knees bent, holding onto a rail with both hands, watching the wreck come closer. The number 553 is painted on her conning tower, beneath a cartoon of a polar bear hoisting a beer stein.
