Gratz's second Shakespeare-based mystery takes on Macbeth. It features the same lovably snarky narrator and clever nods to the Bard, with plenty of information about Scottish lore.
When a roadside psychic predicts that his friend Mac will win the Scottish Highland Games, Horatio Wilkes is skeptical. But when Mac's grandfather, Duncan, is murdered and Mac's girlfriend Beth starts acting increasingly strange, Horatio sets out to find out what happened. Will he able to solve the murder and win the girl while ducking the punk bagpiper group that's out to get him? (Dial, Oct., 272 pp., $16.99, ISBN: 9780803736665, HC, 12 and Up)
