Lest Darkness Fall — L. Sprague de Camp

A Step Out of Time

One minute archeologist Martin Padway is casually ambling through modern Rome. In an instant he is inexplicably hurtled back through time to 6th Century Italy--just before the Dark Ages.

With one foot firmly rooted in the 20th Century, and the other planted tentatively in the Gothic Era, Padway--now Martinus Paduei, Quaestor--uses his wits and his knowledge to change the course of history.
