Casanova's Escape

The survival of our organization, The Rombo Code, hangs by a thread... Our longest-serving and leading member, Mr. Rombo, has been found and captured by our enemies, The White Cube. Mr. Rombo was the guardian of one of the organization's most valuable secrets: The true account, written by Giacomo Casanova himself, of his famous escape from the Los Plomos prison, where the Inquisition confined him for his "dissolute" behavior. We do not know what secrets the famous document hides, but we do know that in 1768, in Bilbao, one of his lovers managed to hide it in-extremis before Casanova was again arrested. Three centuries passed, until a stubborn history professor, an expert in the mysteries of 18th century Europe, discovered and guarded the documents. That man is actually Mr. Rombo, who was captured today in his office... However, not all news is bad, we know that the assault did not result in the theft of the documents. Before being captured, Mr. Rombo created a complex encryption system so that only other members of The Rombo Code can find them. We know that someone has called the police who, by our calculations, will appear at the office in 60 minutes. Your mission is to recover the documents and escape before this happens. And Mr. Rombo? Don't worry, that's another story.
