Officer Krupke

"'Good thing they didn't notice I'm not really a police officer.' — Officer Krupke."

Appearance
Officer Krupke is actually a journalist, disguised as a police officer to sneak into the crime scene before the police arrive. He wrote an article about The Illusion Murders.

Personality
Krupke is not the brightest bulb out there — but perhaps that's only an act while he's working undercover. He was definitely smart enough to figure out a way to get pictures for the newspaper he works for.
