In a room sit three great men, a king, a priest, and a rich man with his gold. Between them stands a sellsword, a little man of common birth and no great mind.
Each of the great ones bids him slay the other two.
‘Do it,’ says the king, ‘for I am your lawful ruler.’
‘Do it,’ says the priest, ‘for I command you in the names of the gods.’
‘Do it,’ says the rich man, ‘and all this gold shall be yours.’
So, who lives and who dies?
