Stop me if you've heard this one: a young lady, newly married, goes to live at her new husband's estate. Creepy goings-on in her new home ensue, and she comes to doubt the integrity of the man she has married. Something Blue puts a neat spin on this hoary old tale by presenting it as a series of letters from the new bride to her sister, in a classical 1800s literary style. You get to "edit" each letter before sending, by changing a sentence here and there. It's interesting how such a relatively small amount of change can really affect the character of the heroine, and therefore the tone of the whole story. She can be fearful and suspicious from the start, making a grim, E.A. Poe-like psychological study, or naive and optimistic to (almost) the end, making a sedate M.R. James-esque ghost story. I encountered two endings, there may be more.
