@madamnaomi, Your story is exquisitely crafted and a joy to read. Though I would have preferred to know what happened to the mystery discovered by the two girls. Perhaps grandma had a solid reason for keeping such a terrifying secret, and indeed that was truly their grandad still alive but hidden.
Thanks for sharing this story, it's a very nice use of the prompt.
Made she did😅
Thanks so much for reading
