THE MYSTERIOUS AFFAIR AT STYLES

On the morning of 18 July, the household at Styles Court wakes to the discovery that Emily Inglethorp, the elderly owner, has died. She had been poisoned with strychnine. Arthur Hastings, a soldier from the Western Front staying at this country manor as a guest on his sick leave, ventures out to the nearby village of Styles St Mary to enlist help from his friend Hercule Poirot. Emily was a wealthy woman. Her household includes her husband, Alfred Inglethorp, a younger man she recently married; her stepsons (from her first husband's previous marriage) John and Lawrence Cavendish; John's wife Mary Cavendish; Cynthia Murdoch, the daughter of a deceased friend of the family; and Evelyn Howard, Emily's companion.
