Fan Casting Lieutenant Arthur Sinclair in Whispers in the Trenches

Lieutenant Arthur Sinclair is a sharp-witted British officer with a reckless streak, masking his fear with dry humor and bravado. Young but battle-worn, he’s wiry, fast-thinking, and dangerously curious—traits that make him both invaluable and a liability. His piercing eyes hold a flicker of mischief, but the war has carved something colder beneath. As the horrors unfold, Sinclair clings to logic, refusing to believe in the impossible—until he’s forced to. When the whispers come for him, his smirk fades, leaving only the quiet terror of a man realizing he may not make it out.
