The narrative follows James Marmaduke, nicknamed Doggie, a delicately reared young man from a staid cathedral town whose overprotective upbringing leaves him ill-equipped for military life. Thrust into the First World War, he confronts mud, danger, and comradeship, survives without distinction or formal honours, and undergoes inward change. Interwoven episodes in England and France show how two women and everyday acts of courage reshape his character, replacing childish dependence with practical resilience. The work balances local color and social observation with a quietly ironic view of heroism and the small-grained moral growth prompted by extreme circumstances.
