# Julius P. Hersheimmer — The Secret Adversary character guide > Julius P. Hersheimmer in The Secret Adversary by Agatha Christie. **Role:** major **Also known as:** Mr. Julius P. Hersheimmer, Mr. Hersheimmer, Hersheimmer, Julius, Julius Hersheimmer **First appearance:** 0007-v-mr-julius-p-hersheimmer ## Snapshot A blunt American millionaire who never met his cousin, Julius crosses the Atlantic to find her and buys his way into the case. ## Who they are Square-jawed, impatient, and refreshingly free of English circumspection, Julius arrives in London with oil money, a guilty conscience, and a missing cousin he has never laid eyes on. He mistakes Tommy and Tuppence for blackmailers, threatens to call a policeman, then offers a million dollars to find Jane — all within a single interview. His fortune and his foreignness make him both a useful ally and an obvious target, and his determination keeps the search alive when official channels stall. ## In the story ### [The Secret Adversary](https://www.betterreads.dev/discover/the_secret_adversary_se/chapters/the-secret-adversary) Arrives in London seeking help to find his missing cousin Jane Finn. ### [Mr. Julius P.
