Are the British the most murderous nation on Earth? Weekends we resolve week’s problems watching stylised dispatch. Or the world’s best detectives? Rebus clicks, Barnaby busts, Marple micro-manages, Taggart targets, Morse decodes, Foyle foils. Or the world’s greatest admirers? Amazed but perplexed by serial circumstances where everyone but the detective and vicar have motives, we like the vicar but admire the detective who proves that the poisoned body found in the mill stream was caused not by the sultry lover or the intolerable woman at the manor, nor her nurse June neither, but the innocuous pharmacist in the High Street.
