Scandal at the Salty Dog

Mystery Stalks the Cobbled Streets of Pirate's Cove
After elderly recluse Juliet Blackwell suffers a mysterious fall in her spooky old mansion, she insists the ghost of long-dead pirate Rufus Blackwell has come to avenge himself on the last member of his treacherous clan.
Bookshop owner and occasional amateur sleuth Ellery Page doesn't believe in ghosts, but he knows fear when he sees it, and it's clear to him his eccentric customer is genuinely terrified.
Who or what is haunting Miss Blackwell, what, if anything, does it have to do with mysterious goings-on at the Salty Dog pub—and why is any of it Ellery's problem?
According to Police Chief Jack Carson, it's not Ellery's problem, and just maybe Ellery should stop asking awkward questions before it's too late.
