Murray Leinster's The Time Tunnel

Murray Leinster's The Time Tunnel is a 1966 TV tie-in novel based on the Irwin Allen television series of the same name that went to air from 1966 to 1967.

I have a soft spot for that television series. It's one of the more interesting time travel series. The novel is quite entertaining as well.

And Murray Leinster is a rather underrated science fiction writer. He certainly wrote some excellent short stories.
