The Cut Throat Cafe

Seth and his talking cat Nightshade arrive in the magical town of Gramichee to gain an apprenticeship: he's finally read to qualify as a magician. But he soon discovers that the existing apprentices are under attack at the town's Scrumdiddlyumptious Caf, which is far more deadly than it is delightful. Seth's got his hands full, as usual. Can he pass his exams, discover who's murdering the apprentices, and stop them before they strike again?
