BelstephA number of years ago I came across
an earlier book that told the same story, somewhat differently. I don't remember it very well but I do remember that one punishment, which Janet describes in "Happy Tears 2" as "Piping Hot" is described more fully in this earlier book.
I believe the title you seek is:
'The Delicious Daughter' by Paul Little. It's not really earlier, though. Little was famous for "stealing" and then adding his own embellishments. The original
Happy Tears was supposed to have been written in the 30's. Little's work spanned the late 50's to early 80's.
You can read more about it here (It seems Clifford had both versions of this story):
