Mafia 5. Seventeen Moments of Spring.

Are you sure someone tried to kill him? I doubt it; who kills someone with books?

There are indications of checks/defenses for the other 3 people. So, it seems there can't be any other explanation. And the second part of the "news" clearly refers to the doctor.

In the morning, it seems I might have been too hasty about Kyle. Perhaps it's just a radio operator.

Regarding the clue about the city, I highly doubt it will refer to a specific city. I would rather look for something like cityhall, townhall, or some bla-bla-city – in general, something with the root "city."
