The secret door. Faller E.

Anna has been working as a guard of time for two years and she has more than enough things. You need to go into the past to prevent a fire and save the paintings of a famous artist, then move the scientist several decades ago to accelerate scientific progress. And if there is time, you can inspect the sights of the city, visit the royal ball or just buy a cute hat for yourself. That is how Anna was going to spend several free days in London of the 19th century before returning to her world. But she did not know that for a long time she would get stuck in the distant past. Travel portals were suddenly destroyed, and the future is in danger. Who is trying to change the course of time? Anna has to figure out what happened and prevent an impending disaster.
