The Time Masters
Author: Wilson Tucker
 
Gilbert Nash has no past.
Secret Service authorities in charge of security for the top secret Ridgerunner Project don't believe that. Everybody has a past, they reason. The trouble is, Gilbert Nash's past they just wouldn't believe even if he told them. It is a past wrapped up in the Project, the first attempt to send a spacecraft beyond the solar system. And the death of one of Ridgerunner's top scientists a few days after seeing Nash doesn't calm Security at all. But there is something else pretty weird going on. The dead scientist's wife doesn't seem to have a past either - and she has disappeared . . .
