The answer to Pablo's riddle was Pablo himself.
He told that to Watson with a smile and his smile sent shivers to the driver's spine.
Pablo's smile made him believe that Pablo really was the one who killed and killed and killed.
"I am sorry, my lord. I will stay silent now."
"Good. And run as fast you can. I will give you money. The Black card gives free access to such rides but I will pay you if you make me reach there before dark."
"Sure." Watson was serious now.
He increased his running speed and he too wanted to drop Pablo as soon as possible.
Pablo rested his head on the walls of the carriage and now he finally found some piece.
"You scared the poor man." Cupid said.
'He was asking for it. And you were finally able to get one riddle right.'
"Yeah. Yeah. If you would have used your brain for something good then you would have finished your job here sooner."
'Shut up.'
