1. A Classic Murder Mystery Book: Crooked House - Agatha Christie

Set in a sprawling mansion complete with an eccentric family, this is a timeless classic that exudes the traditional elements of a whodunit: secluded country house, plenty of clues and pretty much anyone could be the culprit.

In this murder mystery book, the wealthy Leonides family find themselves living amongst a killer when their beloved father and grandfather perishes - thanks to a poison administered by what could only be one of them... Surely not?

Charles Hayward, fiancé of concerned Miss Leonides, is sent to the (not-so) little crooked house outside of London to delve into the family's strange dynamic. While uncovering family secrets and hidden desires, the question remains: who killed the cunning Aristide? A perfect example of the favourite 'closed circle' plot so often featured in the golden age of detective fiction, it will have you guessing and doubting yourself until the end!

Not so welcome in her new village any more and facing the prospect of prison, she must throw on her amateur sleuth hat and uncover the source of the poisonous ingredient in her shop-bought quiche.
