Four Days of Doubt

"...We're not taking the submarine," Arista said, once the initial excitement of Squishy's gesture had settled enough for actual planning to begin. "Not this time. Not until I've solved the three-hundred-meter failure properly, and I don't want to rush that fix just because we've got a fresh lead."

Bram nodded, unsurprised. "Surface exploration, then. Nettle's boat."

"Exactly. Slower to actually reach any real depth, obviously, but considerably safer while we figure out exactly what we're even looking for."

Bram considered the plan for a moment, then frowned slightly. "...If the mermaids are living below the surface, which seems likely, given everything we know about the Drowned Court, how are we supposed to actually find anything from a boat? We'd just be sailing over open water with no way to see what's underneath us."

Arista sat with that, the gap in the plan landing properly. "...That's a genuinely good point."

"Could we mount Colm's sonar system on the boat itself?" Bram asked. "The mechanical stylus, the whole seismograph setup from the submarine. If it worked mounted on a sealed hull, I don't see why it couldn't work mounted on a surface vessel instead."

Claire considered the question seriously. "...The core mechanism doesn't actually require a submerged hull to function. It needs a tube extending into the water, a copper plate detecting pressure waves, the spring-loaded ball, and the stylus recording the results. All of that could mount along the underside of Nettle's hull just as easily as it mounted on the submarine's exterior."

"The only real difference," Colm added, already sketching the modified placement, "is that we'd be reading from considerably further above whatever we're trying to detect, compared to actually being submerged near it. Signal strength would be weaker, less precise. But for detecting something as large as an entire settlement, or even just significant underwater structures, it should still register clearly enough to be useful."

"...So it's a downgrade in precision," Arista said, "but it lets us survey without needing to risk the pressure failure again."

"Exactly that trade-off," Claire confirmed. "Rough detection from the surface, safely, versus precise detection from depth, at genuine risk until the hull material's actually fixed."

Bram nodded, satisfied with the compromise. "I'd rather have rough data safely than precise data with a repeat of the foam incident."

"Agreed," Arista said, already sketching the mounting bracket for Nettle's hull. "We're not trying to map every detail of wherever the mermaids actually are. We just need to detect something, a structure, a settlement, any sign of significant activity beneath the surface, enough to narrow down where to actually focus once we're ready to go deeper properly."

Nettle, reviewing the proposed modification to her own ship, nodded easily. "Shouldn't take long to mount. I've got the hull space, and the crew's handled trickier installations than a single sonar tube."

"Good," Arista said, already finalizing the plan. "Mount the sonar, follow Squishy's bearing, survey as we go. If we find something significant, we mark it properly, and figure out the actual approach once we know what we're dealing with."

Bram studied the growing plan, genuinely satisfied with the caution built into it. "...This feels considerably more careful than most of your plans usually start out."

"I learned that lesson the hard way, at three hundred meters," Arista said, wry. "I'd rather move slow and safely toward an actual civilization than rush in blind and discover a second material failure at the worst possible moment."

The story has been stolen; if detected on Amazon, report the violation.

"Growth," Bram said, grinning.

"Growth," Arista agreed, already directing the crew toward Nettle's ship to begin the modification. "Let's go find some mermaids. Carefully, this time."

They set sail the following morning, Nettle's ship cutting steadily along the bearing Squishy had indicated, Colm stationed at the newly mounted sonar, tracking the seabed's rough contours as they went.

The first day passed uneventfully, the ship holding a clean, confident course.

By the second day, the doubt started creeping in.

"...Are we sure about this," Bram said, watching open, empty water stretch endlessly in every direction, no sign of anything remotely significant on Colm's readouts. "We're basing this entire expedition on a tentacle gesture. A single, imprecise, non-verbal gesture from a creature who may or may not have actually understood what we were even asking him."

"He understood something," Arista said, though even her own confidence had softened somewhat by the second day of empty ocean. "Whether that something was 'the mermaids live this way' or just 'I am also curious about that direction' is admittedly a fair question."

"We might have projected an entire meaning onto a gesture that meant nothing specific at all," Claire admitted, checking the sonar readouts one more time, finding nothing but ordinary seabed and open water. "Krakens don't naturally communicate in cardinal directions. We might be reading intention into something that was closer to a shrug."

"...A shrug," Bram repeated, flat.

"It's possible," Claire said, unable to fully dismiss the concern despite her own hopeful investment in the theory. "We don't actually know how much genuine understanding passed through that connection. Bram himself said it wasn't real telepathy, just an impression."

Bram sat with that, glancing at the trident still resting carefully in his lap. "...I felt something get through. I still believe that part. I just don't know how much of what came back was an actual answer, versus me desperately wanting there to be an answer."

By the third day, the crew had settled into a strange, uneasy rhythm, hopeful, then doubtful, then hopeful again, watching Colm's sonar readings with the same anxious attention a gambler might give a spinning wheel.

"...Nothing," Colm reported again, checking the soot paper's steady, unbroken line. "Ordinary depth variation. Nothing structural, nothing anomalous."

"How much further can we reasonably go before turning back?" Petrov asked, ever practical, checking supply levels against the ship's remaining range.

"A little further," Arista said, though her own certainty had thinned considerably by this point. "If we've genuinely misread Squishy, better to find that out properly rather than turning back the moment things get uncertain."

Nettle, at the helm, glanced back at the assembled, increasingly anxious crew. "For what it's worth, my gut still says continue. I don't know why. Call it instinct."

"...Instinct isn't exactly rigorous data," Claire pointed out, though not unkindly.

"No," Nettle agreed. "But it's gotten me this far in life."

They pressed on through the fourth day, tension climbing steadily, every hour of unbroken, empty sonar readings chipping away a little further at the crew's collective confidence.

Then, mid-afternoon, Colm's stylus jumped.

Not a single spike, the kind they'd seen countless times before from rocks or curious sea life.

A pattern. Steady, rhythmic, circular: spikes registering in a consistent, repeating arc, as though something enormous and continuous stretched in a wide ring directly ahead of them.

"...Wait." Colm sat up straight, watching the pattern trace out with mounting, disbelieving excitement. "That's not natural terrain. That's not a creature either. Look at the shape, it's circular. Consistent. Repeating at even intervals."

Arista crossed the deck fast, watching the strange, rhythmic pattern emerge across the soot paper. "...That's not random. That's structured. Deliberate, even, in its own way."

"Temperature readings are climbing too," Claire reported, checking a secondary gauge she'd mounted specifically to monitor water conditions. "Significantly. Something's heating the water directly ahead of us, in a pattern matching that same ring shape."

Bram stared out toward the horizon, where, faint but unmistakable now that they knew to look, a thin line of disturbed water shimmered against the afternoon light, bubbles, rising in a steady, continuous line, stretching as far as they could see in either direction.

"...Four days," he said quietly, "and Squishy's tentacle gesture just turned into the single most promising lead we've had this entire journey."

Arista stared at the shimmering, bubbling line ahead of them, feeling the doubt of the past three days evaporate entirely, replaced by the same old, familiar restless thrill of a genuine discovery finally within reach.

"...Slow approach," she said, already moving toward the helm. "Whatever that is, we don't sail into it blind. Let's find out what we're actually looking at first."
