The Time Tunnel (****)

I would NEVER have found this book were it not for the wonderful recommendations that arise from my fortunate ownership of Yahoo's reading group "Classic Sci-Fi". If you enjoy that old time stuff from the pulp era, you might like to check us out. Here's a link to our home page and here's my review:

From the very birth of the conception of time travel, sci-fi authors and scientists alike have wrestled with the difficulties of time travel paradoxes most commonly expressed in the question of what would happen if you killed your grandfather during your trip to the past. In “Time Tunnel”, Murray Leinster has treated his readers to what was probably the first (and quite possibly the best) instance of the infuriating mental tangles that one can encounter when the immutability of the progression of real time collides with the flexibility of time travel.

Leinster has crafted a positively ingenious combination of characters into a fascinating novel of high adventure that will both delight and fascinate his fans – a scientist who felt compelled to change the past in order to rescue the future from an impending atomic war between China and the US; young lovers who, fearing for their lives in a war-torn modern world, felt compelled to flee to a safer past; a 20th century burglar and con artist who realized the early 19th century was ripe for the plucking; and a playboy who was horrified to watch his grandfather die unmarried and childless.

The story begins in 1964 when Harrison, completing research for his PhD thesis in the Bibliothèque Nationale in Paris, discovers long-buried correspondence showing that, in 1805, a gentleman named de Bassompierre had written to certain scientists handing out modern knowledge long before its acknowledged discovery. In one case, for example,

“He wrote to Laplace, the astronomer, assuring him that Mars had two moons, very small and very close to its surface. He also said that there were three planets beyond Saturn, and that the one next out had a period of eighty-four years and two moons, one retrograde. He suggested that it should be called Uranus. He added that in the year 1808 there would be a nova in Persis, (which there was!) and he signed himself very respectfully, de Bassompierre.”

When Harrison and his friend, Pepe Ybarra, reach the conclusion that de Bassompierre was a time traveler who is attempting to change the future by handing out modern ideas before their time, the high jinks begin in earnest and the time travel conundrums drop into the readers’ laps at a dizzying pace.

And the ending … sigh! What a wonderfully clever simultaneous resolution of both the adventure plot-lines and the time travel paradoxes.

Recommended as a scintillating addition to the library of any reader who savours classic sci-fi from the pulp era.
