In the book "Constellation of Vital Phenomena" (Anthony Marra) Sonja remembers visiting anatomy and pathology museum in London. There she stumbles upon an exhibit of a skull of a cannibal. The placard says:
"There are no characteristics to distinguish the cranium of a cannibal from that of an ordinary man"
The next line says:
"The morbid association between the cannibal and the nutcracker..."
I am not sure I understood what association Sonja (or, rather, the author) had in mind. Is it simply due to the fact that Sonja bought the nutcracker the same day she visited the museum? I guess there is greater significance attached to it, something I failed to notice.
