Nobody talks about this one. A detective show where the protagonist is a girl who can literally see the logical structure of crime scenes, and the 1995 animation lets you watch her inner eye work through the mathematics of murder. Each case is a puzzle that respects your intelligence enough to give you the pieces first, then watches you realize you misread them. The show trusts you to solve it before she does. Fifty-six episodes means it never rushes, never explains away a contradiction with a handwave. By the final arc, you realize every case was teaching you how to see the way Alice sees.
