Kassim’s first instinct was to chase every vehicle seen near Salum’s house. Upendo stopped him. Panic was exactly what the kidnappers wanted. They photographed the room, recorded the broken lock, and listed what was missing. Only Salum and a folder of old dam maintenance maps were gone.
The numbers on the wall were not a plea. Kassim recognized them as the designation of Service Gate 317, a maintenance entrance removed from Kaskazi’s updated plans.
Before leaving, he reviewed the bribery video that had been circulating online. Two seconds before Salum received the envelope, a child cried in the background and another figure appeared in a window.
The clip had been cut before the conversation.
Kassim remembered the day: his mother had been awaiting emergency surgery.
That context did not erase the bribe, but it proved the editor had removed material that complicated the accusation.
Halima asked whether he was prepared to discover that Salum was still working with the company.
“I will follow the evidence even if it leads home,” Kassim said.
“But I will not let Kaskazi decide which part of my father’s truth is visible.”
They split the search. Halima stayed at the school to protect copied land records. Upendo contacted the national police and dam authority. Kassim, two village youths, and an elderly dam technician named Kondo headed toward Gate 317.
The path crossed forest and abandoned construction yards. At one point they found a recent boot print over an old concrete survey mark. Kassim measured it and kept moving. Near the dam, a security patrol blocked the road. Its leader, Sergeant Lusekelo, claimed the gate did not exist.
Kondo laughed. “I repaired its ventilation fan before you learned to wear a uniform.”
Lusekelo searched Kassim’s bag and seized his tablet under the suspension order. Kassim had anticipated that. The device contained only public layers and an automatic log of every file opened. The real evidence was distributed across other accounts. When Lusekelo powered it on, the action itself was recorded.
They were released after Upendo called from the district office and demanded a written arrest basis. Kassim noticed a broken-chevron motorcycle tyre mark near the patrol vehicle. It matched the tracks at the missing stones.
At dusk, they reached a ravine below the dam. Vegetation concealed a steel door marked 317. The lock was new.
Kondo found an old ventilation shaft and lowered a phone camera through it.
The screen showed drilling pipes, bags of black ore, and Salum tied to a chair.
A man beside him demanded locations of the remaining survey monuments. Salum gave false coordinates, moving each answer farther from the real river line. Even under threat, he was trying to waste their time.
Kassim wanted to break in immediately. Kondo pointed out that the tunnel ran close to the dam foundation. A careless explosion or forced entry could damage the structure. They needed evidence, rescue, and safety in that order—or all three would fail.
Using a directional microphone, Kassim recorded the interrogator referring to “the old Hydro Studies agreement.”
Upendo searched company records and found that Mrema had once been a director of Black River Hydro Studies, the firm involved in Salum’s original survey scandal.
The current project was not a new abuse. It was the continuation of an old one under a new name.
Halima sent a message: rain was forecast upstream, and Kaskazi had announced a sudden “controlled water test” for the next afternoon. If the company opened the lower gate while villages were still occupied, it could create the flood its map had predicted.
Kassim transmitted the video from the shaft to three independent recipients. Then he and Kondo cut the ventilation grille and crawled inside.
They freed Salum, but before they could reach the exit, a truck reversed above the shaft. Wet concrete began pouring through the opening.
Kaskazi was sealing the tunnel with them inside.
