About this book:

When the last ship flees the advancing Arctic ice, six men are left marooned at a magnetic observatory on the roof of the world—with a severed radio line, a missing supply drop, and a saboteur in their midst. Disgraced physicist Arthur Miniver knows the numbers don't lie: the earth's magnetic field is shifting violently beneath their feet, and the tiny steel curling he found inside a locked instrument housing proves someone has been tampering with the science. But in a place where the sun won't rise for six months and the temperature drops fast enough to freeze breath in the air, the most dangerous variable isn't the magnetism—it's the man sitting across the table.

Colonel Sterling calls it discipline. Dr. Vance calls it a joke nobody's laughing at. Radio operator MacRead hears only the dead silence where a rescue signal should be. And somewhere in the long polar night, the aurora writes green fire across a sky that offers no witnesses. As the station's instruments record anomalies that shouldn't exist and the coal supply dwindles, old grudges and buried secrets thaw in the close heat of the common room. The magnetic needle isn't the only thing swinging wildly off true north.

*Murder at the Magnetic Observatory* is a masterclass in atmospheric historical noir—where the locked room is an entire frozen archipelago, the ticking clock is the spring thaw, and the killer hides in plain sight behind a veneer of scientific camaraderie. For fans of *The Terror* and *The Silent Patient*, this is polar isolation pushed to its breaking point: a puzzle box of a mystery where the solution lies buried in the data, the dark, and the human heart.
