On this island, there are three types of people. Knights, who always tell the truth, knaves, who always lie, and spies, who can do either. In these puzzles, you meet three people, one knight, one knave and one spy. The challenge is to determine who is who.
A says "I am a Knight"
B says "A is a Knight"
C says "If you asked me, I would say that A is the spy"

Who is A?
