How does Jim Butcher use imagery in Death Masks?

In terms of Molly Carpenter, it is interesting to consider the meaning and implications of the book's title. The motif, or repeated image, of an individual using some kind of mask or lie to conceal a truth occurs several times throughout the novel. It often takes place within the context of some sort of connection to literal or metaphorical death, but also takes place on less intensely dramatic circumstances. Molly's change of clothes (i.e from what she wants to wear into what her parents want her to wear) is a relatively low key manifestation of this motif, but an evocative one nonetheless.
