I was just rereading The Martian Chronicles for the first time in many years, and I hit a strange little note.

About the third major story in, "Though the Moon Be As Bright" - the one with the first successful expedition to land on Mars, which they discover to be now dead due to infection from the first two expeditions - there is a drunken lout among the crewmen who goes on at length about his wild times with a blonde named Ginny.

The story was published in 1948, so it would have been written about the time that Robert and Leslyn were divorced and waiting out the decree nisi, and he was all but living with Virginia. Bradbury had a noted, obnoxious passion for Leslyn and (IIRC) remained friends with her for some time after the divorce.

A deliberate slap at "the other woman"? Or just a coincidence?

I don't know, but I would think if it was intentional, the lout would be going on about "wild-times with a red-head named Ginny."

Actually, there is no evidence Bradbury stayed in touch after the divorce. What happened was that Forry Ackerman ran into Leslyn a few years down the road, put her back in touch with Bradbury, who then sent her a box of books. There may be correspondence, but no public record of it exists.
