The whole thing started when the clock on the Metropolitan Tower began to run backward, and then the tower, and everyone in it, went sliding thousands of years back into the past.

Murray Leinster's 1919 story is a landmark early time-travel tale. Inventive, prophetic, hugely influential. Read it for a foundational SF classic, a Manhattan skyscraper and its office workers hurled back to the age before the city, and their ingenious struggle to survive and return, from a founding master of the genre.
