One snowy night, Detective Anderson was in his house reading a book. All of a sudden a stone came crashing through his window, breaking it.
Anderson got up and looked out the window just in time to see three neighborhood brats who were brothers run around a corner. Their names were Alan Jones, Mark Jones and Peter Jones.
Not knowing of Anderson's reputation as a genius detective, the two innocent brats teased him by sent a note with clue on Anderson's front door.
The note reads "? Jones. He broke your window."
Which one of the three Jones brothers should Anderson question about the incident?
