A rare manuscript was stolen from a library shelf. The thief left behind a pair of muddy boots. The librarian stated that it had been pouring rain outside all afternoon, and every visitor tracked mud inside. However, the detective noticed the mud on the boots was completely dry and chalky white. Where did the thief actually come from?
Chalky white mud
The mud was chalky and dry, which does not match the wet brown mud outside from the rainstorm, indicating the boots came from a limestone cave or dry quarry.
