The Murder at the Vicarage

Enter the small town of St Mary Mead in the first of Agatha Christie's full-length Miss Marple mysteries, following the shrewd and sheltered white-haired Jane Marple through her amateur sleuthing and crime solving ventures. The Murder at the Vicarage launched the beloved series of twelve novels.
Everyone hated Colonel Protheroe. And soon after Reverend Leonard Clement says that it would be a favor for someone to kill the dreadful man, Protheroe does turn up dead-in the reverend's study, no less. The Murder at the Vicarage follows Miss Marple's scrupulous investigation into her huge pile of suspects for the murder, turning a sleepy English village into a puzzle of clues only she can slot into place.
