While other children were devouring the works of Enid Blyton and Beatrix Potter, Carla Valentine was poring through the pages of Agatha Christie novels - and that early fascination lead to her job as a pathology technician working in mortuaries and trained in forensics.

Nearly every Agatha Christie story involves one - or more commonly several - dead bodies, and for a young Carla, a curious child already fascinated with biology, these stories and these bodies were perfect puzzles.

Of course Agatha herself didn't talk of 'forensics' which, in the way we use it now, but each tale she tells twists and turns with her expert weave of human observation, ingenuity and genuine science of the era. Through the medium of the 'whodunnit', Agatha Christie was a pioneer of forensic science, and in Murder Isn't Easy Carla illuminates all of the knowledge of one of our most beloved authors.
