I have an idea for a short story collection. I’ve written the first two and drafted the next 10 - I would be aiming for between 20-25 depending on world count.
I have changed names but the point is you are supposed to pick up on references (say for example, stories written from Spike’s point of view in Buffy with name changes - it’s not that, by the way). If you change all names of characters and places but you notice the connections, is it infringement? Do you need to do anything?
