antithetical to his nature – prison. The man renowned for his sterile
surroundings and obsessive hygiene is now forced to endure the grime and
communal living of incarceration. This stark contrast is immediately apparent as

gloves, and the shared, less-than-hygienic toilet. Yet, despite these
challenges, the Professor maintains his intellectual curiosity, viewing his
imprisonment as a unique opportunity to study crime from a firsthand
perspective.
