Forum: Lost Stories

I remember lots of little details but not the author. Boy gets kidnapped by a serial killer but rescued. Serial killers father is rich and starts looking after the boy like a grandfather. When he is old enough he starts giving the boy properties owned by his late son.
It was a series of 3-4 stories and was never finished.

I have to look up some authors, but believe "dark" is part of the author name or story title. Try Dark days by Reluctant Sir. https://storiesonline.net/s/18210/dark-days-darkest-before
