Never Smile at Strangers

The story dives into the mind games between characters, but I'm wondering if it reflects real psychological tactics or if it was heightened for tension.

The setting felt claustrophobic and tense, almost like another character. I'm curious if the author drew from real places or crafted it entirely from imagination.

Throughout the book, characters seem to drop their guard easily, which added to the suspense but also made me question their judgment. Did anyone else find this realistic?
