The Six Napoleons
'I checked the dates in old newspapers. I found out that the pearl vanished exactly two days before Beppo was arrested for attacking someone. And this attack happened in the factory of Gelder & Co., at the very moment when the busts of Napoleon were being made. Now you can clearly see how things happened, though of course when I started the case, I saw the last things first. Beppo had the pearl. He may have stolen it from Pietro, he may have stolen it with Pietro, or he may have been taking it from Pietro to his sister. It is of no consequence to us which answer is the correct one.
