A library in a residential district. Many books and few readers. Patriarchal quiet and calm reign in these halls—seems like time flows there more slowly than behind its thick walls… But how deceptive impressions can be—not only the first, but also the second. In an instant, all the powers of evil seem to descend on those who work there, tying them into one fatal knot. Murders, kidnappings, and “no matter where you throw it—everything’s a dead end,” plus an age far from “maidenly” and not exactly Hollywood looks—and help comes not from a knight in shining armor, but from a homeless man who himself needs saving… But Anna is a librarian, a person who reads a lot—so she’s thinking. And she has friends too, which means she’s “no one’s easy prey”—but do “all” know that?
