The serial “A Thousand Years a Minute” concludes after three more installments of Adventures in the Unknown, as Ted and Alan shoot a triceratops, rescue a caveman, fight off a giant snake in a river, and then get captured by more cavemen, but freed by the one they helped. Not awful, but this is not Rip Hunter, Time Master by any stretch.
Their next serial, “The Infra Red Destroyers,” begins with the following issues, All-American 13, though according to the story a year has passed between issues 12 and 13. Ted and Alan get a cover appearance with the opening chapter of this serial, which it frankly does not merit. They story, which runs to issue 18, is an overly complex mess of meteor-missiles from Venus, an invisibility ray, a mad scientist, an innocent man framed for murder, an inquisitive reporter, and giant Venusian snakes who want to take over the world. The White House, Washington Monument, the Empire State Building and big chunks of New York City get destroyed in this storyline, but the art fails to make any of that look impressive. The Venusian snakes turn on the mad scientist and kill him just before Ted and Alan wipe them out with poison gas.
Their final storyline, “Rescue on Mars,” runs from issues 20 – 25, and sees the two men return to Mars to retrieve Professor Lutyens, bringing along their new buddy Jack Williams. Alan has invented a metal that will not melt, and foreign spies are pursuing them, but that’s largely a distraction from the main story. Jack gets to play the hero, putting a robot head over his own (which works remarkably well at tricking the other robots). We discover the Lutyens brain is back in his old body, and the professor constructs a robot to help them escape, which they do. They land on Earth near some Japanese troops, but Lutyens still has his old paralysis ray gun, and uses it on them.
The series ends at this point, as I am sure upon returning to the US the professor and the boys are grabbed by the intelligence services and put to work creating weaponry for the US military.
