"The Missing Will" by Agatha Christie is a short detective story featuring the famous Belgian detective Hercule Poirot, written during the early 20th century. The narrative explores themes of intellect and determination as it follows Poirot as he investigates the unusual terms of a will left by a wealthy uncle to his niece. The story presents a delightful puzzle infused with Christie's trademark wit and clever plotting. In this tale, Poirot is approached by Miss Violet Marsh, the niece of the late Andrew Marsh, who challenges her intellect with a will that promises her inheritance only if she can outsmart him within a year. Following her uncle's death, Poirot and his friend Hastings visit Crabtree Manor to uncover the hidden second will or a concealed sum of money, believing that the deceased uncle, known for his intelligence, has devised a clever test for his niece. As they navigate the quaint manor and gather clues, they encounter various obstacles and red herrings. Ultimately, Poirot reveals the true will, which had been cleverly hidden in plain sight, proving that intelligence and reason, rather than mere educational qualifications, are the keys to success.
