What, No.6 hiding an envelope in the stone boat! An envelope containing blank sheets of paper, he must be mad! Mind you, the person who placed that seat in the main cabin of the stone boat must have been having a laugh. I mean have you been this cabin of the Stoneboat? You have to crouch down, as No.'s 2 and 14 are doing as it is. So how are you supposed to sit in a seat?
And No.2, what exactly did he expect to find written on those blank sheets of paper? A report on the Village perhaps, a report on him perhaps. I wonder if those two technicians in the laboratory heated those blank sheets of paper, testing them for lemon juice?
