Upon learning of the Emperor's location, Cavour wasted no time and quickly left the embassy, heading towards the train station as he needed to catch the next available train.
This scene was observed by the Ministry of Internal Affairs' surveillance personnel stationed around the Sardinia Embassy. They followed Cavour from a distance and, after he had purchased his train ticket and left, they discreetly showed their credentials to the ticket seller and inquired about the train Cavour had booked.
Upon seeing the Ministry of Internal Affairs' insignia, the ticket seller was visibly startled and stammered out the information.
After learning which train Cavour would be taking, the Ministry's personnel quickly left the ticket counter, but not before threatening the ticket seller to keep it confidential.
The ticket seller nodded repeatedly in fear and then watched them leave.
Subsequently, they returned to the Ministry and reported the news to Minister Percy.
