The water stretched out as far as the eye could see in an expanse of gentle grey-blue swells broken only by the occasional white-capped wavelet and the line of the ship's passage, unrolling die-straight behind us until it faded into the glare of sun on the western horizon. Directly below where I stood, dominating my vision if I leant my upper body over the rail, the churn of the great screws dug an indentation in the surface, followed by a rise just behind. Like the earth from a farmer's plough, I thought dreamily, cutting a straight furrow across three thousand miles of sea. And when the ship reached the end of its watery field, it would turn and begin the next furrow, heading east; and after reaching that far shore it would shift again, ploughing west. Back and forth, to and fro, and all the while, beneath the surface the marine equivalents of earthworms and moles would be going busily about their work, oblivious of the other world above their heads. The farmer, the ship, above; the insect, the fish, below. So peaceful. Peacefully sleeping, while occasionally a seed would fall and take root in the freshly split furrow . . .

“Russell!” Holmes exclaimed, and the sharp voice and his sudden hand on my arm snatched me awake and sent my hat flying. I grabbed at it, but too late; the scrap of felt sailed out behind the ship, floating on the air for a long time until eventually it planted itself into the brine furrow. I turned to my husband.

“Why did you have to startle me like that?” I complained. “That was my last warm hat.”

“Easier to purchase another hat than to fish you out of the sea,” he said. “You were on the edge of going over.”

“Don't be ridiculous, Holmes, I was just watching the patterns made by the propellers. What did you want, anyway?”

“The first bell for dinner went a bit ago. When you didn't come to dress I thought perhaps you hadn't heard it. And when I came down the stairs, it appeared as though you were trying to throw yourself over.”

His laconic words bore just the slightest edge of true concern, as if a question lay behind them. I reached up to adjust my hair-pins, only to find them gone—weeks after chopping off my thick, waist-length hair (a necessary element of disguising myself as a British officer) my hand was still startled to find the weight of it missing from my head. Spreading my fingers instead to run them through the brief crop, I glanced back at the straight path laid out behind us, and felt a shudder play up my spine. Perhaps I shouldn't lean over any more rails while I was as tired as this, I told myself, and allowed Holmes to thread my hand through his arm and lead me back towards our cabins.
