Noir needs a city, and Renata Okafor has built one. Tsiolkovsky Station hangs at the Earth–Moon L5 point in 2119, a two-kilometre O'Neill cylinder with forty-one thousand residents, three competing air utilities and a legal system that is mostly insurance law with a badge. Into this arrives Dele Marchetti, a claims adjuster for Hanseatic Orbital Mutual, sent to determine whether the death of a hydroponics technician in a pressure-sealed bay was accident, suicide or something that will cost the company money. Lagrange Point Blues is a whodunnit, a why-dunnit and a where-does-the-oxygen-come-from-dunnit, and Okafor keeps all three spinning without dropping a wrench.
What it's about
The dead man is Yusuf Adeyemi-Roth, a mid-level grower in the station's Ring Four farms. The bay he died in was locked from the inside, logged as sealed for a fumigation cycle, and the air scrubbers report nothing unusual. Marchetti's brief is simple: prove it was suicide, void the policy, go home. Instead he finds a black market in scrubber capacity, a union that is quietly rationing its members' air, and a station administrator whose reelection depends on a habitat expansion that the numbers say cannot be breathed. Okafor structures the book in "spin days", and each chapter's header notes the station's rotation count, a small trick that gives the investigation a relentless, mechanical clock.
Why it stands out
The genre's usual weakness is that the science becomes wallpaper. Here the science is the crime. Every clue depends on how a rotating habitat actually works: Coriolis drift on a dropped tool, the pressure differential between rings, why a body decomposes differently at 0.8 g. Okafor, who spent a decade as a loss adjuster in Lagos and Rotterdam before writing fiction, understands that the most frightening people in any system are the ones with spreadsheets. Marchetti is a wonderful lead: tired, morally flexible, quietly kind, and genuinely good at his job. The prose is fast and funny in the Chandler mode without descending into pastiche; the similes are about air and orbit, not rain and cigarettes.
How it compares
Readers of James S. A. Corey's Leviathan Wakes will recognise the detective-in-a-habitat set-up, but Okafor keeps the scale small and the politics local, closer to a city council than a system war. There is a strong flavour of William Gibson's Sprawl novels in the corporate texture, and of Adam Roberts's Jack Glass in the locked-room ingenuity. Compared with Sarah Gailey's or Tade Thompson's genre-blending, Okafor is more classical: this is a mystery first, and it plays fair. If The Salt Cartographers is the year's slow tide, this is its riptide.
Pros
- A locked-room mystery whose solution depends on real orbital mechanics
- A protagonist who solves things through paperwork and empathy, not fists
- Air as economy, politics and weapon, worked out convincingly
- Propulsive pacing; most readers will finish in three sittings
Cons
- The supporting cast is large and a few names blur in the middle third
- A romantic thread is under-developed and could have been cut
- The final confrontation leans slightly harder on coincidence than the rest of the book has earned

Film rights were optioned in February; take the usual pinch of salt.
Who should read it
Mystery readers who have never tried science fiction, and science fiction readers who want a plot that clicks shut like an airlock. It is the easiest recommendation on this list for a long flight. If you finish it wanting something bigger and stranger, step up to The Archive of Unfinished Suns.
Verdict
Third place for a book that does exactly what it promises and then a little more. Lagrange Point Blues is the most fun we had with a novel this year, and the one we most expect to see on screen. Score: 8.6 out of 10.
