Trimming the spoiler from the IMDB review, which rightly focuses some attention on Leslie Brooks, a gal who definitely coulda been a (noir) contendah...

A woman is ordering a tombstone for Edith Marie Harrison, she is not sure of the date of death but when she is asked her name states it is Edith Marie Harrison!!!

This is one the more ambiguous entries from "The Whistler" series. It was an anthology series with Richard Dix portraying different characters (always on the dark side) in each movie. In this one he plays Ralph Harrison, an artist, a bit of a ladies man who is tied to his wife's purse strings. He claims to his latest conquest, Kay (Leslie Brooks) a beautiful artist's model that he and his wife have a special understanding and that her health is so bad she is not expected to live. In reality, he relies on his wife's money as his amateur paintings don't sell and the "friends" that attend his parties snigger about him behind his back. He is also desperate for female companionship as Edith is bedridden but Edith has a secret - she has been exercising every day and is now fully cured. She plans to surprise Ralph at his studio but when she hears a conversation between Ralph and Kay, her face shows there is no "special understanding"!!

Leslie Brooks had a bewitching beauty and a knowing smile and proved here that she should always be given "bad girl" roles. If Audrey Totter was Queen of the Noirs, Brooks was the Princess but, like Totter, she was at the wrong studio, in this case Columbia and by the time she hit her stride in "Blonde Ice" she soon retired for married life. With a few cynical looks and that arch smile it was hard to believe her Kay was the innocent model who was content to wait until Ralph's wife died in the legal, conventional way. Ralph doesn't want to wait though and when Edith takes to her bed again in despair he tries to help her along with poison!!!

When they return from their honeymoon Kay, fuelled with suspicion from the housekeeper (Claire DuBrey, whose biggest role was as Bertha Rochester in 1934's "Jane Eyre"), who knew exactly what her late mistress's marriage was like, starts to suspect that Ralph is a murderer...
