Four men, one of whom has committed a crime, made these statements:
 
Arch: "Dave did it."
Dave: "Tony did it."
Gus: "I didn't do it."
Tony: "Dave lied when he said I did it."

If only one of them lied, then Dave is the criminal.

Some people are average, some are just mean.

Assuming, furthermore, that each of them either lied or told the truth (i.e. excluding statements that are unconnected to reality), and that lying equals telling untruths (rather than, say, trying to convince someone of something you believe to be untrue)

Tony had only just met the others. He thinks that Dave is Arch, but says what he says becaus Gus told him to.
