I waved victoriously at the submarine, imagining happily that the good doctor’s head was set to explode from frustration. The craft had by then begun to move away, and was circling around as if turning tail for Carnforth in defeat. “He’s showing us his back, the dog,” I said to St. Ives. “Slinking away.” But the submarine continued to turn in a close circle, not slinking away at all, and soon the light was aimed dead at us, its watery glow obscuring the shadow of the ship behind it. Abruptly it launched itself forward, flying at us in an increasing rush.
CHAPTER 7
The Turning of the Tide
I gasped out a warning to St. Ives, who shouted, “Hold on!” at that same moment. He was bent over the controls, high-stepping our awkward craft across the sea floor now, attempting to maneuver us out of the way of the approaching submarine, which veered to remain on course. I held on with an iron grip, watching our doom hurtle toward us. The submarine easily compensated for our creaking, evasive ploys, and within moments we were blinded by the intensity of its light, and we both threw ourselves to the deck, hands over our heads, as if we could somehow protect ourselves.
The chamber toppled backward, and we were thrown together in a heap. I banged my elbow into something hard, but scarcely felt it, fully expecting the rush of cold water, the desperate, futile flight through the hatch. But there was no rush of water, and I had no sensation of our craft having been struck by anything. The light from the submarine was gone. The submarine had passed over us, and we found ourselves dragged along backward at what seemed to be a prodigious rate. It was our friends above, hauling us out bodily. We were “packing it in” as Fred had put it, right on time, and there was no dignity involved in the packing. I gripped the stanchions that supported the circular seat, and looked up through the port at the dark ceiling of our grotto, and once again I saw the flotsam held in stasis against the sands.
Then the blinding light again, and the submarine swept past, inches overhead, its dark shape passing like a great whale, and I thanked my stars that we were tipped flat, for the submarine evidently didn’t dare to swim any closer to the sea floor. But my musings were shattered by a heavy jolt, and now out of the port I saw that we had bulled our way straight into the coach and four. A rain of human bones tumbled out through the window. Our retracted arm hooked into the bottom of a horse’s skull, which sailed along with us like a misplaced figurehead before another jolt knocked it free. Then suddenly we were ascending smoothly, and we hauled ourselves gratefully onto the seats again, taking stock of bruises and abrasions.
We passed through the stasis layer into the murk of the sands, St. Ives letting out ballast to aid our ascent, and I reminded myself not to be quite so prematurely satisfied in the future, gloating over a victory before the enemy had left the field. Now we were clear, though. He could hardly follow us into the pool of quicksand. “Nothing broken?” I asked St. Ives.
“My chronometer, I’m afraid.” He held up the shattered timepiece. “I’d rather break an arm, or very nearly. But not a bad bill to pay, all in all.”
We continued to ascend in silence for another minute or two, but then abruptly stopped.
“Perhaps a fouled line,” St. Ives said. “They’ll be at it again directly.”
But the minutes passed, and still we sat there, my mind turning in the silence. It came to me that I should make a clean breast of my long-held suspicions while I had a quiet moment. “I’m a little worried about an element of this entire business,” I said.
“Out with it, then.”
“We’ve had some good luck,” I told him. “And it seems we’ve been clever. But consider this: what if Frosticos knew what we were about, and I mean from the beginning. That business at Merton’s — knocking poor Merton on the head like that — what if it was meant to move us to action? For my money Frosticos wasn’t foxed by the false map for more than a moment. He knew we had the original, and he intended for us to lead him to the box. He provided us the means by lending us this diving chamber. We were at the mercy of the tides once we arrived here at the Bay, and it was no great feat for him to lurk about the subterranean reaches watching for us when the time was right. Then he played a helpful light on our endeavors until we had succeeded, at which point he tried to murder us in cold blood, having done with us.”
St. Ives sat thinking, but there was only one element of the theory that required any thinking. He reached up and gave us another gasp of air. “You say he wasn’t foxed by the map,” he said carefully. “You’re suggesting…”
“I don’t mean to suggest anything,” I said, looking out into the by now thick sands, “only that we might have been played like fiddles.”
“I sense that you don’t want to cast any blame on Finn Conrad, but he might easily be the necessary link in the chain? His appearance outside Merton’s was certainly convenient.”
“It was,” I said, “although it’s as easily coincidental. Perhaps Merton’s forgery was simply no good, and Frosticos saw through it.”
“You’ve seen his handiwork,” St. Ives said.
“Yes, but suppose Frosticos had come here straightaway by some subterranean route and had already found the map useless before our arrival, thereby suspecting it to be a forgery and lying in wait for us. When he saw us in our lighted chamber meddling on the sea floor…” I shrugged and gave us more air.
“But we’ve got to consider that Finn was our means of finding the boatyard and discovering this chamber. We were forced to flee in it in order to avoid drowning or being shot by men who seemed to have known we would come along when we did.”
“One other thing,” I said. “You were careful to slip the true map into your coat pocket, but Merton wasn’t half so careful, especially with his insanely detailed letter, which he placed directly into Finn’s hands before sending him post haste to the Bay.”
“I find the idea distressing,” St. Ives said wearily. “I don’t say that I find it unlikely, just distressing.”
“I’ve been distressed by it for the past days,” I told him, “and I should have spoken up earlier. But I like the boy, and I don’t want to malign him, especially when there’s the chance that he’s innocent. Perhaps we’re as shrewd as we think ourselves to be, but it looks very much as if Frosticos has been leading us along like blind men.” I watched the unchanging view through the port, worried that they were taking an infernally long time, and slightly unhappy with myself for having laid out my suspicions about Finn Conrad like a trial lawyer while insisting that I didn’t want to malign him.
“For the moment,” St. Ives said, “let’s remember that all their machinations have been in vain. We’ll keep a weather eye on Finn, just for safety’s sake, but we’ll not condemn him until we’re certain.”
“Good enough,” I said, and abruptly we began to rise again, jerky and quick, and within moments we burst out into the dawn twilight, dripping watery sand, having been reeled in ignominiously, but alive. I saw straight off, however, that something was amiss.
The wagon was tilted disastrously, headfirst into the sand. Fred had untied the team, their forelegs covered with ooze, and was leading them away. Finn stood by him, but I saw that Hasbro lay over the back of one of the horses, unconscious or dead. Fred glanced back at us with concern evident on his face, and when St. Ives opened the hatch Fred shouted, “Remain very still, lads. Your friend’s been shot. He’ll live to tell the tale. There’s nothing for you to do for him.” He pointed up the bay before turning away.
