I mentioned Girls Crystal elsewhere and here is a link where you can read a few of the detective stories in pdf form:- http://www.friardale.co.uk/Girls%20Crystal/Girls%20Crystal.htm
And here is the main storypaper page:-http://www.friardale.co.uk/Story%20Papers.htm
Most of these entries are there because of the Bunter author, Charles Hamilton but lots of other odd stories on here.
If you go to the home page and read the intro. it should set your mind at ease if you are concerned about copyright problems. I think.
