Axelrod's Experiment on the Moon

"I have no intention of demolishing my official research work by introducing something so far out as claiming I've seen extraterrestrials working away on the moon," Axelrod told Ingo. "We will be in touch with you in some other fashion, which I will make sure you recognize," he added. The mysterious Mr. Axelrod had provided me feedback, as promised, where there could be no doubt that it was his jolly self that sent Leonard's book to me."
