Machine Testimony

A machine can't testify. Its frame can.

Two crushers lie dead in the sealed pump room of the ore hopper Cinders-Fall, parked in the Cassini Division between Saturn's great rings. The hatch dogs are galled tight in their seats. The oxygen valve is shut while the gauge still reads pressure. The underwriter wants a crew-error ruling, because crew error means the families get nothing.

Silas Calder, a sixty-year-old Lead Fatality and Loss Adjuster with a bad knee and a micrometer he trusts more than people, came to Saturn Local Drift 02 to settle that claim. He brought his partner: Unit 7-R, "Sev," the compliance android he was saddled with on his last case, which still corrects him by regulation number.

Then a salvage agent claims Sev as abandoned property and seals himself in the records bay to inventory it. When the hatch opens, the agent is dead against the bulkhead, Sev is standing exactly where it stood, and its log has a 47-second gap.

Under the Outer Charter Code, a synthetic present at a death is decommissioned in 72 hours, and its memory core is wiped. That core is the original evidence against the man behind thirty-two scheduled "accidents," and somebody wants it gone.

Calder has three days, a superintendent who goes by the book, a court on Ceres more than two hours away by message, and a superconducting magnet next door that keeps firing with no one at the controls. Worse, the evidence keeps pointing at Sev. The lab matches the smear on the dead man's collar to Sev's own hydraulic fluid, and Calder rebuilt that arm himself.

His rule has always been that the metal doesn't lie. This time it says his friend killed a man.

Why you'll love The Terminal Void Casefiles:

• Fair-play locked-room mystery: Every field line, tool mark, and drop of hydraulic fluid is on the page, so you can solve the case alongside Calder.
• Hard sci-fi that does the math: Superconducting magnets, quench physics, light-lag deadlines, and forensic chemistry you can check.
• A partnership put on trial: The friendship forged in The Iron Coffin meets the one case where Calder can't measure the answer. Perfect for fans of The Expanse, The Murderbot Diaries, and Raymond Chandler.

Book 2 of The Terminal Void Casefiles. It works as a standalone, but readers will get the most from it after The Iron Coffin.
