"Subject did not cast Expected shadow."

In the winter of 1962, the Arco Desert of Idaho was home to the National Reactor Testing Station...a 900-square-mile "cathedral of the atom" where the government performed the dangerous alchemy of the nuclear age. It was a place guarded by hardened veterans, high-voltage fences, and the most advanced sensors the Cold War could buy. They were prepared for Soviet spies. They were prepared for radiation leaks.

They were not prepared for the Visitor.

Drawing from redacted Department of Energy logs and declassified security reports, James Cawley reconstructs the ten-month psychological siege of a facility that shouldn't have been breachable. From barefoot tracks that vanish into untouched snow to thermal signatures that dissolve into static, The Midnight Visitor explores a haunting "locked-room" mystery where physics fails and the observers become the observed.
