By morning he will be dead in his sealed study murdered by his own ancestral crossbow. All eyes turn to Stephen Pike Tithe Hall's newest under-butler. Fresh out of Borstal for a crime he didn't commit he is the wrong man in the wrong place at the wrong time. His unlikely ally? Miss Decima Stockingham the foul-mouthed octogenarian family matriarch. Together this mismatched duo must navigate secret passages buried grudges and rising terror to unmask the killer before it's too late...
