The daughter of a distinguished soldier, Bess Crawford follows in his patriotic footsteps, volunteering to serve her country as a nurse during the Great War. In 1916 she promises Lieutenant Arthur Graham that she will carry his dying request to a brother. When Bess arrives at the Graham house in Kent, Jonathan Graham listens to his brother's last wishes with surprising indifference.

Years before the Great War summoned Bess Crawford to serve as a battlefield nurse, the indomitable heroine spent her childhood in India under the watchful eye of her friend and confidant, the young soldier Simon Brandon. The two formed an inseparable bond on the dangerous Northwest Frontier where her father’s Regiment held the Khyber Pass against all intruders. It was Simon who taught Bess to ride and shoot, escorted her to the bazaars and the Maharani’s Palace, and did his best to keep her out of trouble.

This box set contains the first four mysteries in this bestselling series.
