something else, too: far in the distance, out toward the broad ocean, the tide was returning. It appeared as a wall of roiling whitewater, lit by the rising sun. How high and how distant I couldn’t make out, but it was moving toward us like galloping doom.
St. Ives saw it, too. He left the box on the bed of the wagon and ran toward Finn. What the boy thought he could accomplish returning to the wagon I can’t say. The only answer was that he was coming to our aid at the peril of his own life, and I was filled with happiness and shame both. Even so, he had chosen the worst moment for his heroics.
I leaned out of the hatch in a fair hurry now and clutched wildly at the crane arm, managing to grab the grappling hook, looking back to see St. Ives stopping Finn in his tracks, urging him back toward shore. Holding onto the grapple, I stepped out across the three empty feet to the tilted bed of the wagon, and suddenly I was falling, the line reeling out of the unsecured windlass. I clutched at the air futilely with my free hand, landing on the sands without a shudder, plunging in knee deep. I could hear Fred shouting, and St. Ives shouting, and out of the corner of my eye I saw Finn catapult past St. Ives and run out across the sands. Fred grabbed St. Ives by the coat now and dragged him back bodily, and St. Ives had no choice but to follow. Together they fled toward shore, not knowing that I was mired and supposing that I would gather Finn up and follow.
I heard the ratchet sound of the windlass crank, and the rope, which was coiled atop the sand like a floating snake, began to retract. I held onto the grapple with both hands, otherwise keeping very still, and after a moment the line went taut, and I began to rise from the sands with the heavy sound of sucking and of gasping as my boots pulled free. I let go with one hand and reached for the side of the wagon, getting a good grip on it, kicking myself up onto the seat and clambering to the bed, where I stumbled to my knees, breathing heavily, half with fear and half with exertion. Finn had jumped down now, and was waving me on and pointing toward the tide, frighteningly close, moving in a long even mass of dark green and white.
Spurred by this sight, I leapt down, heeding Finn’s admonition to run, but when I glanced again at the tide I saw that I could not. The quarter mile to shore was simply too far. Fred and St. Ives would be hard pressed to save themselves. To the north, the hillock of sand from which the doctor’s henchmen had been shooting was empty. They’d seen the advancing sea and gone away like sensible men.
“To the wagon!” I said to Finn, and the two of us climbed back up onto the bed, which was canted steeply downward, its stern to the tide. Finn’s face wore an avid sort of lunatic joy, as if this were an adventure rather than a death sentence. My own thoughts were equally lunatic—that the wagon might save us, and that I might save the abandoned device, which had taken a disastrous toll over the years. I was damned if we’d lose it now. I shouted at Finn to lash himself to the mast of the crane with the line from the grappling hook, and I picked up the box and staggered to the front of the wagon, where the diving chamber hung with its hatch open. I spun half around with the effort of throwing the box, nearly pitching off into the sands again, but I was dead on. It crashed through the open hatch, the ocean-corrupted case knocking itself to flinders, the device sliding beneath the seat.
When I turned around the Bay behind us was a shimmering, rapidly expanding sea, its leading edge billowing and surging forward at a height I wouldn’t have thought possible, and I could do no more than throw myself down on the bed of the wagon and latch onto the crane mast like a limpet before the tide was upon us. The waters slammed into the wagon, throwing a wave of cold ocean across our backs at the same moment that it pitched the rear of the wagon upward and
