Often, before the others woke each morning, Ali would see him flickering off upon the black water, not a riffle in his wake. At such times she wishfully imagined this was the real man within him. The sight of him slipping monk-like into the wilderness made her think of the simple force of prayer.
He quit using paint and simply blazed the wall with a pair of chemical candles and went on. They would float past his cold blue crosses glowing above the waters like a neon JESUS SAVES . They followed him through the apertures and rock meatus. He would be waiting on a scarp of olivine or reefs of iron, or sitting in his night-colored kayak, holding on to an outcrop. Ali liked him at peace.
One day they drifted around a bend and heard an unearthly sound, part whistle, part wind. Ike had found a primitive musical instrument left by some hadal. Made of animal bone, it had three holes on top and one on the bottom. They beached, and some of the flute players took turns trying to make it work for them. One got a trickle of Bach out, another a bit of Jethro Tull.
Then they gave it back to Ike, and he played what the flute was meant for. It was a hadal song, with clots of melody and measured rhythm. The alien sound spellbound them, even the soldiers. This was what moved the hadals? The syncopation, the cheeps and trills and sudden grunts, and finally a muffled shout: it was an earth song, complete with animal and water sounds and the rumble of quakes.
Ali was mesmerized, but appalled, too. More than the tattoos and scars, the bone flute declared Ike's captivity. It was not just his proficiency and memory of the song, but also his obvious love for it. This alien music spoke to the heart of him.
When Ike was done, they clapped uncertainly.
Ike looked at the bone flute as if he'd never seen such a thing, then tossed it into the river. When the others had left, Ali fished along the bottom and retrieved the instrument.
They made a sport of sighting hadal footpaths. Where the caverns narrowed and the shore vanished, they spied foot- and handholds traversing above the waterline, linking the riverside beaches. They found strands of crude chains fixed to the walls, rusting away. One night, failing to find a shore to camp upon, they tied to the chains and slept on the rafts. Perhaps hadal boatmen had used the lengths of chain to haul upriver, or hadals had clambered barefoot across the links. One way or another, the ancient thoroughfare had clearly been connected.
Where the river widened, sometimes sprawling hundreds of meters across, the water seemed to stop and they sat nearly becalmed. At other times the river coursed powerfully. You could not call rapids what they occasionally ran. The water had a density to it, and the cascades poured with Amazon-like torpor. Portaging was seldom necessary.
At the end of each 'day,' the explorers relaxed by small 'campfires' consisting of a single chemical candle laid on the ground. Five or six people would gather around to share its colored light. They would sit on rocks and tell stories or mull over their own thoughts.
The past became more explicit. They dreamed more vividly. Their storytelling grew
richer. One evening, Ali was consumed by a memory. She saw three ripe lemons on the wooden cutting board in her mother's kitchen, right down to the sunlight spangling off their pores. She heard her mother singing while they rolled pie dough in a storm of flour. Such images occurred to her more frequently, more vividly. Quigley, the team's psychiatrist, thought the distracting intensity of their memories might be a form of dementia or mild psychotic episode.
The tunnels and caves were very quiet. You could hear the hungry flipping of pages as people read the paperback novels circulating among them like rumors. The tap-tap of laptop keyboards went on for hours as they recorded data or wrote letters for transmission at the next cache. Gradually the candles would dim and the camp would sleep.
