Way Station (Clifford Simak, 1963)

Its hero Enoch Wallace first appears as a mystery man: an impossibly young-looking Civil War veteran, 124 years old and still living in his parents' remote Winconsin farmhouse. Nowadays this building has a glittering, Tardis-like interior, ever since Wallace was recruited by aliens as stationmaster on a minor branch line - not a railway, but Galactic Central's network of matter transmitters carrying passengers between the stars. Earth isn't ready for this secret, and countryman Wallace's best friends are extraterrestrials and ghostly simulations.

When the CIA investigates his reclusive lifestyle, it accidentally stirs up an interstellar diplomatic crisis. Wallace's job, and his place in the countryside he loves, are suddenly threatened. So are his hopes for persuading Galactic Central to step in and halt our accelerating slide towards nuclear war.
