Years before The Demolished Man, there was Bester’s probable man. I looked forward to reading it as the first story of my retirement, and I enjoyed the time-travel model that Bester set up: David Conn travels backward from 2941 to World War II, but then returns to a vastly changed future. For me, though, I found the naÏve attitude toward war unappealing.

Apparently, time travel has rules. For example, you cannot go back and simply take something from the past—it must be given to you. Thus, our man from the future must talk young Oliver Wilson Knight and his girlfriend into giving up the 1990 almanac that they bought in 1950.

By night, Addyer dreams of traveling to different times; by day, he is a statistician investigating an anomalous increase in the country’s population centered right in the part of the country that took the heaviest radiation damage in the war.

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.

Travel diary of blasé tourists around the Solar System, to other stars, back in time to the Great Fire of London and to another galaxy.

When Professor Henry Hassel discovers his wife in the arms of another man, he does what any mad scientist would do: build a time machine to go back and kill his wife’s grandfather. He has no trouble changing the past, but any effect on the present seems rather harder to achieve.
