The Reverend Dodd, vicar of the quiet Cornish village of Boscawen, spends his evenings reading detective stories by the fireside – but heaven forbid that the shadow of any real crime should ever fall across his seaside parish. But the vicar's peace is shattered one stormy night when Julius Tregarthan, an ill-tempered magistrate, is found at his house in Boscawen with a bullet through his head. The local police inspector is baffled by the lack of clues. Suspicion seems to fall on Tregarthan's niece, Ruth – but surely that young woman lacks the motive to shoot her uncle dead in cold blood? Luckily for Inspector Bigswell, the Reverend Dodd is on hand.
