The Last Hope Diamond is a priceless diamond owned by Mrs. Vandereel.
When Mrs. Vandereel bought the diamond she brought along the curse of the Red Skull who stole it. So she hired Mystery Inc. to get it back. They stopped him at the town graveyard, unmasking Vandereel's own butler, Stuyvesant, who swore revenge.
