The Black Tower (Herculeah Jones Mystery)

At the eerie Hunt mansion, Herculeah Jones has been reading aloud to Lionus Hunt, an elderly stroke victim who can only communicate by blinking his eyes (once for yes, twice for no). Mr. Hunt seems to be trying to tell Herculeah something, but his gruff nurse won't allow her to ask any questions. What is Mr. Hunt trying to say? Is it related to a murder that took place in the mansion's black tower years ago? And who is the creepy old lady who lives in the mansion? Herculeah's friend Meat thinks she may be asking for trouble, but Herculeah Jones won't quit until she gets to the bottom of this mystery.
