You are totally right. What I thought about was "The Scarlet Pimpernel" by E. Orczy which has a similar plot.

I also read a comment that Scaramouche - The Scarlet Pimpernel - The Three Musketeers are interconnected.

Which also reminds of this find in one of my previous posts - PURIM + MASKS + MORDECHAI = it is alway about the secret helper of persecuted people - and they celebrate that every year with a special day!

"On Purim we dress up with masks and costumes. This seemingly superficial custom is laden with deeper meaning. On Purim we remember that in the world, nothing is as it seems. The real world lies beneath all the superficiality.

In fact, the words Megillat Esther, the Scroll of Esther, also means to reveal (megaleh in Hebrew) the hidden (haster). The Purim story peels back the mask and reveals that which is hidden.

Many of the main characters in the Esther story wear masks, not identifying who they really are or what their true motives are.

Haman pretends to have the only the king’s best interests in mind when he advises the king to annihilate the Jewish People, pretending that the Jews are a threat to his kingdom since they follow their own laws and customs, and not those of the rest of Persia.

In reality, he sought to destroy the Jews for his own evil genocidal wishes, as he was the descendant of Amalek, the ancient biblical tribe that was best on the destruction of the Jewish People.

Mordechai never reveals that he is a relative and friend of Esther’s; he pretends to be a simple person who happened to save the King’s life. It is Esther who reveals it to the king at the end that Mordechai is her dear relative.

And of course, Esther herself wears a mask; she pretends to be a gentile queen, never revealing her Jewish identity, until the very end of the Purim story."
