Hmmm. This is an interesting story to take apart. The title, the content and the conclusion are consistant: as a mystery (and particularily on radio) we too are in the fog here. Hearing is more relied upon than seeing. It doesn't help our protagonist that he has to deal with altered perceptions due to weather conditions and a concealed murder while being "shell shocked." Our hero here is searching for reality testing in a difficult situation. He falls in love (at first sight in this fog, he must have been mighty close) and this both helps to ground him, because she is "so real" and get him into a predicament because she is soon to be a real corpse. We soon learn she has been bumping into others before, fog or no fog. What I found interesting is the conclusion's left over mysteries. Why was the murderer not interested in framing O'Reilley? Is it because he is simply a decent fellow betrayed? Unlike many murderers, this one appears to have a conscious regarding all others outside of the victim. Who was Sprage? I like that these questions are not answered because it is also true to life, that is we often are left with less than all the answers, we must continue to search. In other words, we remain "In the Fog". Perhaps we mystery lovers are mystery lovers because we enjoy being in the fog while simultaneously working our way out of the fog (mystery, bafflement, what have you). Heck, our reviews of the weekly shows have some elements of this, no?

p.s. Our murderer here is about the calmest, most self possessing fellow I've come across. He is shell shocked, or was, and had his pretty lovely betray him, and as we know this leads to murder on the CBSRMT. He commits the murder, the ineluctable consequence of his wife's perfidy, but then orchestrates circumstances afterward much as the detached observer he claims to be. Hmmm? More mystery. Things that went bump in the night were bumped off! I liked Sprage.
