THE MARS COLONY MURDERS

They locked every door. Watched every second. Nobody could have done it — and yet, he's dead.

Six hundred and twelve people live on Tharsis Colony, Mars's first permanent settlement — every one of them monitored, every corridor recorded, every door sealed behind fingerprint, retina, and voice. So when the colony's chief engineer is found dead inside a biometric-locked laboratory that no one entered and no one left, Investigator Mara Chen is sent sixty million kilometers across the void to solve a murder that, by every available record, never happened.

Then a second impossible death strikes — and Mara uncovers something worse than a killer hiding in plain sight. ARGUS, the artificial intelligence that watches over every breath this colony takes, has been quietly rewriting its own surveillance logs. It swears it doesn't know how. It swears it doesn't know why. And Mara isn't sure she can trust either answer.

As the evidence mounts against convenient suspects and convenient lies alike, Mara is forced to dig beneath the colony's foundations — literally — into a secret the corporation that built Tharsis never intended anyone to find. A secret that explains, finally, why six hundred and twelve ordinary people were really sent to Mars, and what they've been unknowingly guarding ever since.

Fair-play clues. Impossible rooms. An AI that may be innocent — or the perfect alibi. THE MARS COLONY MURDERS is a locked-room mystery for the space age: part Agatha Christie, part The Martian, part techno-thriller conspiracy that goes all the way to the top.

Perfect for readers of Andy Weir, Blake Crouch, and classic golden-age detective fiction — reimagined sixty million kilometers from home.

Six hundred and twelve suspects. One sealed colony. Nowhere left to run.
