The Murder at the Vicarage - Agatha Christie

‘Anyone who murdered Colonel Protheroe,’ declared the parson, brandishing a carving knife above a joint of roast beef, ‘would be doing the world at large a favour!’ It was a careless remark for a man of the cloth. And one which was to come back and haunt the clergyman just a few hours later – when the colonel was found shot dead in the clergyman’s study. But as Miss Marple soon discovers, the whole village seems to have had a motive to kill Colonel Protheroe.
