Lady, Lady, I Did It!

The protagonist feels so layered and authentic—I'm curious whether this was based on real detectives or purely fictional creation.

The story seemed to take its time unraveling clues, which made me wonder if the pacing was a deliberate choice to deepen the mystery.

The narrative carefully balances clues and red herrings, making it hard to predict the ending. What do you think led to this effective suspense-building?
