To great critical acclaim, author Charles Todd introduced protagonist Bess Crawford in A Duty to the Dead. The dedicated World War I nurse returns in An Impartial Witness, and finds herself in grave peril when a moral obligation makes her the inadvertent target of a killer. As hauntingly evocative as Todd’s award-winning, New York Times bestselling Ian Rutledge novels, An Impartial Witness transports readers to a dark time of war and involves us in murder, intrigue, and the fascinating affairs of a truly unforgettable cast of characters.
