Unidentified Aulus-killing innkeeper

According to a story a Roman soldier told to Gaius Cornelius Calvus, an innkeeper, whose name is unknown, murdered a man named Aulus who was staying in his inn in Megara. The innkeeper hid Aulus’s body in a wagon under manure, planning to leave the city, but Aulus’s friend, Septimus, who was not staying in the inn, learned of this in a dream in which he was apparently contacted, by unknown means, by Aulus himself. Septimus reported him and the people of the city punished the innkeeper, even though Septimus does not seem to have had any evidence against him.
