The year 1940 is in the courtyard. Hard changes. However, at such a large-scale time, no one could relax. You got to London and got to such an urban residential place, which is very quiet. Agatha Christie was smoking tobacco at the same time and talking to you:

—Do you want to work here?Well, I can be your tutor for the Royal Family protection entrance exam. First, tell me your name.

Agatha Christie threw away her tobacco and got up from her chair. She expects answers from you.
