I was seriously addicted to Encyclopedia Brown stories when I was a kid. Someone brought up the books on a discussion board, and I was amazed that I could still remember the ending explanations.
"How can he know the knife was short if it was still buried in the watermelon?"
"He was punched in the chest yet he put his glasses on right after the bully ran away!"
"The happy baby is dancing on a hot car hood that was just driven for hours."
"The guitarist without pads on the tips of his fingers is the fake. Guitarists develop calluses on the tips of their fingers after years of playing."
Were you a fan, and can you still remember the endings?
