Here are the stories I’ve found so far.
Josh Lanyon’s The Dark Farewell was my favorite of the three. Information page at Samhain. Grieving veteran David Flynn meets spiritual medium Julian Devereux while a serial killer ravages smalltown 1920s America. I wanted this one to be longer!
Less romance-y and more historical fiction/erotica is Lanyon’s Out of the Blue, also available in Kindle format. This one is set while the war is still going on, amid a group of pilots. Again, I wanted the story to be longer; I was intrigued by the characters and wanted to know what happened to the relationship once the war ended; did it continue, or fizzle? But perhaps Lanyon was more interested in relationships under high pressure.
In contrast, the novel-length Whistling in the Dark (Kindle) and print by Tamara Allen is much lighter in tone. It’s set post-war in New York City, with two young veterans. It’s got a lot of fun historical detail, particularly about early, early radio.
