After all of K.'s encounters with women in the novel, we get, in Chapter 10, one last woman. Only this time it's an anonymous woman, and K. is following the woman, rather than the other way around. It's as if the novel is stressing again the close connection between K.'s sexuality and his criminality by having this figure shadow his last moments.
