When you're Dutch, I know a site where the complete Bob Evers series by Willy van der Heide can be downloaded (PDF mostly). I devouerd those when I was about ten years old. And they have a kind of cult-status in the Netherlands.
As far as I can find all the work is legal even when the author ' just' died in 1985.
Then again, if you aren't Dutch I wouldn't bother.
If someone is interested let me know and I'll post a link.
