Synopsis: Dr John Bentley is a man living in a scary world. As he becomes consumed with fear that the Iran hostage crisis might lead to nuclear war, he purposes to build a time machine so he can escape what appears to be the inevitability of his world's fate.
He creates a cabinet (which incidentally has roughly the same exterior dimensions as the Doctor's TARDIS) which is a functioning time machine. He goes back through time looking for an era of relative peace. In each time period, though, he finds they all have their own crises—the Black Death, the Spanish Inquisition, the barbarism of Rome. Eventually realizing that life is inherently dangerous, regardless of the time period, he goes back to 1980 where he decides to "face the problems of our own time . . . and solve them!"
Notes: This story appears to have had some sort of involvement by Jack Kirby. First there is a signature of "Kirby" in the first panel. Second, the story feels much more American than British. The art backgrounds appear to represent New York rather than any British location, and the story speaks of the "Iran Crisis", which was a much bigger deal for Americans than the British. Plus, the general artistic style just looks very Kirby-esque.
Aside from the name "Kirby" there appears to be another signature on the story, but it is too indistinct to even hazard a guess as to whom it might be.
