This is the first part of a likely series, with the theme of "What's a little____ between friends?" I'm not sure if I'll stay alphabetical, but I'm starting that way, with a story about consensual adultery between a man and his best friend's wife, with the full knowledge and approval of the husband, even his participation at times, such as their first encounter, a "devil's threesome."
A story in the Dark Tales Universe
When an old friend invites Josie and 3 of their friends from college to visit for a week on the California Coast for a "Hen Party", none of them have any idea that things will change drastically.
Friends of a woman learn someone plans to assassinate her. With only a few days to react, they initiate a plan to rescue her while letting those behind assassins think they were successful. This alters the destiny of both the woman and her friends.
