Ms. Stiletto (Italian: Isabella, duchessa dei diavoli), is a 1969 historical adventure film, directed by Bruno Corbucci.

By chance, she encounters François de Bassompierre and gets the opportunity to reclaim her title but Château Salins is now possessed by Von Nutter.

Therefore, Isabella is barred from possession of Château Salins by the Louvre and a young viscount, Gilbert de Villancourt is assigned as a guardian to her.

However, following a failed assassination attempt by a minion of Von Nutter, Isabella vows to avenge her family and take Château Salins back.

[3] The film was part of a minor trend of comic strip adaptations that emphasised mild sado-masochism and late 1960s fetish gear, which started with Danger: Diabolik and Barbarella.
