Manny Brot, a private eye, embarks on a mysterious journey involving three riddles. The first riddle challenges him to create a shape with zero area, which he solves by infinitely subdividing a triangle. The second riddle involves finding a shape with finite area but infinite perimeter, leading him to the concept of the Koch curve. The final riddle requires a shape that looks the same at any magnification, introducing the concept of fractals. Through these challenges, Manny explores complex geometric concepts in a narrative style.
