A crime has been committed and there are ten suspects. Precisely one of the suspects is a knight and the remaining nine are liars.

George said Arthur did it, Arthur said Bill did it, Bill said Chuck did it, Chuck said Fred did it, Eddie said Fred did it so Fred confessed and said that he did do it.

Harry said Eddie did it, Dave then confessed that he did do it- so John also confessed and said that he did it. Finally, Ian said that he didn't do it.

If George didn't do it, one of the ten suspects did do it - who committed the crime?

Now  I agree 100%.
