Fish thief is the 53th puzzle from The Curious Village.
When you weren't looking, someone came by and gobbled up your fish dinner. The three brothers near the scene of this dastardly crime had this to say: A:"Me? Oh yeah, I ate it. It was good too!" B:"I saw A eat that fish right up!" C:"B and I didn't eat that fish." One of these three brothers is lying to you, but which one is it?
