W. P. Shervill
Best known for brisk historical adventures for younger readers, this early 20th-century novelist set stories against moments of war and medieval England. Very little biographical information seems to survive, which gives the work an extra air of mystery.

About the author
W. P. Shervill is a little-documented author whose surviving reputation rests mainly on two historical novels now widely available through Project Gutenberg: Two Daring Young Patriots; or, Outwitting the Huns and Edgar the Ready: A Tale of the Third Edward's Reign.
Those books suggest a writer drawn to action, loyalty, and big historical backdrops. Two Daring Young Patriots is a juvenile novel set amid the First World War in Belgium, while Edgar the Ready turns to the age of Edward III, showing a clear taste for adventurous history written for younger readers.
Beyond those works, reliable biographical details are hard to confirm from the sources I found, so it is safest to remember Shervill through the books themselves: lively public-domain tales that carry readers into danger, courage, and patriotic feeling.
