A pirate's treasure, lost for decades, lures the greedy and adventurer alike. Did someone commit murder to get their hands on it? When the celebrated biographer of the infamous pirate Blackheart takes a suite at the Mayfair Hotel to live out his final months, Goliath the porter is desperate to ask the one question that has haunted treasure hunters for decades: Where is the loot buried? Forbidden to disturb a guest, he instead visits the man writing the author's own life story, only to discover him dead at his desk. Accused of the crime, Goliath turns to Cleo and Harry to clear his name. As they investigate, the danger escalates when a description of Goliath is splashed across the front page of the newspapers. It's only a matter of time before someone connects the hotel porter to the manhunt, and to Harry, who is secretly hiding him. The hotel is already under siege from the press, as word spreads that Blackheart's biographer is in residence. The tantalizing link between the treasure and the murder fuels a frenzy, disrupting the hotel and driving away high-profile guests. With suspects including a titled heir and a man claiming to be Blackheart's secret grandson, can Cleo untangle fact from fiction before Goliath is discovered and the hotel's reputation is ruined? And, more importantly for some, will the location of the hidden treasure finally be revealed?
