Who had seen the assassin 's knife , and where is it now ? `` In any event , '' argued the prisoner 's counsel , `` the prosecution must prove , beyond any reasonable doubt , that the prisoner committed the murder . The prosecution must show that the mysterious individual who entered the house at three o'clock in the morning is not the guilty party . To be sure , the clock indicated eleven o'clock . But what of that ? I contend , that proves nothing . The assassin could turn the hands of the clock to any hour he pleased , and thus deceive us in regard to the exact hour of the crime . ''
