When Conan sees a man with a cane being followed into an alley, it didn't take a detective of his skill to guess what was about to happen. Sticking close to the alley walls, he follows after them while talking full advantage of being light enough to have very quiet footsteps.

And then when they come to a stop, he steps out directly behind the prospective thief and makes a loud remark.

"It isn't nice to steal things from people, you know."
