Premise: Saboot (English: "Proof") is an Indian crime series based on the "howdunit" format with Anita Kanwar, returning from a six-year hiatus, playing the lead role of CBI officer and Chief of Homicide, Inspector KC. Though it was inspired by many crime series, the "howdunit" format and KC's "dishevelled appearance and clumsiness" was based on Columbo.
Hypothesis: Howdunits are more popular than whodunits.
