Even before I found Asimov and Heinlein and other books with space ships on the spine in the
local library, I stole this paperback from my dad’s shelf around 1964. As you can see from
the picture, it had an irresistible cover (yes, that’s the stolen copy).
For the most
part, Bestor’s story has jaunting (teleportation through space) with no time travel, which
is enough to cause plenty of excitement for Gully Foyle (aka Geoffrey Fourmyle) as he jaunts
around the war-torn solar system, seeking revenge on various space merchants. But at one
climactic point, he also manages a jaunt through time.
And then he was tumbling down, down, down the space-time lines, back into the dreadful
pit of Now.
