Chapter 56: The Six-Minute Crossing

Alder pressed the probe beneath Elias’s smallest toe and watched his face.

“Anything?”

“A profound sympathy for unemployed toes.”

Neral’s stylus paused. Mara failed to hide a smile. Even Cassian looked briefly less like a man attending his own indictment.

The probe moved along the outer edge of Elias’s foot.

“Here?”

“Nothing.”

That sobered the room.

Alder covered his foot and flattened the blanket over the immobilized knee. Pain climbed through the joint in slow iron pulses. Below it, the numbness remained offensively calm.

“Ten minutes,” she said. “Oral participation only. No standing, reaching, evidence handling, or offering to demonstrate a staircase.”

“I had choreography.”

“I am preserving it for a less medical audience.”

She left a wrapped sugar sweet on his blanket, this time within reach.

Elias inspected it. “Bribery?”

“Pain management for your personality.”

Mara’s laugh was small, but for three breaths they were tired people around a bed instead of witnesses around a breach.

Then Alder turned the clock toward them.

Neral recorded the restrictions, including Alder’s immediate and unappealable authority to terminate Elias’s participation for pain, medication, or any lapse in attention.

“Accepted,” Elias said.

The evidence occupied one lamp-lit table: duplicate C-4 stub, Stair Nine latch scraping, black cloth, and recovered brass wedge, each separately sealed. Mara checked every number against the paired recovery cuts. Cassian’s independent first-seal impressions matched the stub and latch packets. Ward blanks, clean C-4 stock, and packet exteriors had all tested negative for K-Six contamination.

No one wasted ceremony on controls that had already spoken clearly.

The stub preserved the complete eighth tear. Inside its folded edge, reagent touched the oily deposit, flashed blue, then formed the narrow rust-colored ring of aged K-Six coolant.

The Stair Nine scraping answered identically.

Residue from the black cloth did the same.

Beneath the preserving spirits lingered a stale wintergreen odor, coolant gone old inside metal. Pale foreign seal dust remained trapped in the cloth’s hem, but its source post was unknown.

“Keep the dust outside the crossing finding,” Elias said. “Interesting is not the same as authenticated.”

Mara opened the witness transcript. “The cloth was first observed wrapped around the upper service latch housing. It was later recovered on the grating near the service throat, after the guard change and bell-line isolation. No witness can say whether it was removed or dislodged.”

“One observed placement and one later recovery,” Elias said. “Not two recoveries.”

Neral cut the distinction onto her slate.

Under magnification, the K-Six deposit lay inside the stub’s folded edge where pressure had compressed the paper fibers.

“The complete tear identifies dose eight’s issued package,” Cassian said. “The trapped residue places that package beneath a portable carrier strap.”

“And matching aged coolant reached Stair Nine,” Mara added.

Cassian nodded. “Dose eight left C-4 in a K-Six carrier. Material from that transfer reached the Stair Nine latch.”

“Not enough,” Elias said.

“The comparison is direct.”

“The route finding is direct. The crossing still has to survive metal.”

He looked to Neral. “Record authorization for a controlled reenactment. No original exhibit enters the mechanism.”

Alder folded her arms but allowed him to continue.

“Use a clean retired carrier shell matching the archived K-Six dimensions. Replace the ampoule with an inert weight. Match the cloth’s dimensions and weave with clean material. The test wedge matches the recovered wedge’s measurements, not its surface marks.”

“Assignments?” Mara asked.

“I do not participate,” Elias said before Alder could enjoy saying it. “Mara controls the latch. Cassian keeps the bell trip and striker in sight. Neral records carrier travel and contact points.”

Cassian glanced at Alder. “And the doctor?”

“Stops the test whenever she likes.”

“Accepted.”

No narrowing. No objection.

Elias regarded him. “You are becoming alarmingly trainable.”

“Your medical judgment is not the institution I am defending.”

“Comforting distinction.”

The boundaries followed: one unobstructed baseline cycle, one weighted crossing with the cloth fitted in the witnessed position, and one immediately following cycle after wedge withdrawal. Binding, uncontrolled release, or new damage ended the test.

“The result can prove route and mechanical feasibility,” Elias said. “It cannot identify the carrier, handler, installer, recipient, approach side, administration status, or destination beyond Stair Nine.”

His knee pulsed hard enough to blur the lamp.

Alder raised two fingers. “How many?”

“Three.”

Cassian said nothing. Mara’s expression lost its humor.

Elias looked down at the packets and read the Stair Nine seal number aloud. Halfway through, he substituted two digits from the C-4 stub.

Alder stopped the clock.

“I can still dictate.”

“You can dictate the wrong exhibit very confidently.”

Pride rose first. Procedure, as usual, arrived with better documentation.

“Record the lapse,” Elias told Neral. “Terminate my evidentiary participation.”

Neral obeyed.

“You will not join the field reconstruction by relay,” Alder said as she prepared the sedative.

“Shared custody remains in force.”

“Cassian and Mara,” she replied. “Your plan survives your absence.”

That was the point of a plan. Elias disliked it anyway.

As cold entered his arm, Mara reached for the sweet. He caught the wrapper first and pushed it toward her.

“Officially transferred.”

“Under protest?”

“Under appetite.”

Her grin was the last thing he saw.

Rainwater whispered inside the conduits at Stair Nine.

Two guards witnessed Mara and Cassian break the temporary joint seal. Behind the upper latch cover, metal sweated beneath the lamps. An oily thaw smear marked the service seam, and stale coolant clung to the housing despite ventilation.
