It’s a while since one of Ultey’s ‘Silurian Tales’ has appeared. Unlike those stories, which feature scientists for the most part exploring prehistoric Earth through a robust time-travel mechanism, the three scientists in this shortish story find them in an altogether graver predicament. Something has clearly gone wrong, and they have a choice of running away from an impending potentially fatal something in the fabric of space and time, or to stop running and face the challenge head on.

As with a lot of the ‘Silurian Tales’, the story is short and inconclusive.
