The voices of A Case of Identity

5 voices in A Case of Identity by Arthur Conan Doyle. Every one is a separate voice, cast to the character as written.

Narrator (narrator) — Watson's first-person literary narration — warm, adventurous, admiring of Holmes.
Sherlock Holmes (protagonist) — The world's only consulting detective. Razor-sharp analytical mind, cold precision, theatrical wit. Alternates between lethargy and explosive energy. Speaks in crisp, certain pronouncements.
Dr. Watson (protagonist) — Holmes's loyal friend and biographer. A former army surgeon, warm, practical, earnest. Speaks with admiration for Holmes and genuine concern for clients.
Mary Sutherland (supporting) — A short-sighted, over-talkative typist and client in A Case of Identity. Naive, trusting, and convinced her missing fiancé will return.
James Windibank (antagonist) — Mary Sutherland's cold, calculating stepfather — secretly disguised as her fiancé Hosmer Angel to control her inheritance. Unmasked by Holmes but untouchable by law.
