When Jacobia "Jake" Tiptree and her friend, Ellie White, agree to refurbish Eastport's most disreputable old dwelling, Harlequin House, pulling up the floorboards reveals something far more sinister than dry rot. A hidden trapdoor unearths the skeleton of a notorious 1920s flapper with a fresh corpse sitting neatly beside her. With a good old-fashioned Maine murder on their hands, Jake and Ellie are hot on the trail of the murderer—but this time more than their reputations may be on the line.
