The first way the novel portrays the theme of identity is through the mandrake dolls. The evil, possessed dolls, go on an evil tear and through that takes the victims identity. The fact is that if your identity is taken, you can’t control yourself anymore. This is seen when Tam Dubh takes control of Adam various times throughout the novel.

The final thing that portrays the theme of identity is the way Adam and Catriona goes and looks back on a diary written a hundred year ago, and translates it to something they can understand.
