I have just found a serial called 'One year later' in old Australian women's weekly magazines from 1945 and 1946. I can't find mention of this story anywhere. It doesn't feature Miss Marple or Poiroit, yet anyway, but is about the apparent suicide of a Rosemary Barton. The story seems a little familiar, but I don't think I've read it before. Has anyone heard of this story or read it?
