Volume 3: The Mystery of the Warehouse Explosion – written but not yet edited.
The Hardy Boys’ old chum Chet Morton – now a buff Earth First! activist and the Hardy Girls’ favorite relative – comes back to Bayport to visit. Immediately a biotech warehouse is blown up.
Can Francesca and Josephine apprehend the real criminals and save Chet – all the while staying one step ahead of Chief Oscar Smuff and the Bayport police.
