An engineer and a patron of the Prague bar where Tereza works. When the obnoxious man insults Tereza, the tall stranger stands up for her. He later asks her to go home with him, and while she initially declines, Tereza ultimately accepts and has sex with him. For Tereza, the tall stranger is a way for her to test Tomas’s theory that love and sex are completely unrelated. Tereza’s encounter with the tall stranger is a complete disaster, but she is left wanting to see him again just so she can see her own naked body in proximity to his. The tall stranger never returns to the bar after his sexual encounter with Tereza, and she is left thinking that he, too, is a member of the secret police and will accuse her of prostitution just like the obnoxious man. Like the young man, it is never confirmed if the tall stranger is with the secret police or not.
