They had a doorway into the past. But it didn't just open on a place on a day. There was a sort of flutter and it caused spatial drift and temporal spread. Two probes might go through together on the twenty-first century side but come out miles and years apart on the Silurian side. This story is part of the author's Silurian Tales series.
