19: The Disappearing Floor - Coming 9/06
The Hardy Boys smash Duke Beeson's robbery gang using the weird inventions of Aunt Gertrude's former classmate, Eben Adar.
Many fans consider this one of the worst written stories in the canon yet it remains a favorite due to its dream-like surreal atmosphere.
UPDATE: Applewood has ceased reprinting Hardy Boys stories and this volume will not be released. :(
