Final answer:
Winterbourne's travels featured the company of his aunt and a courier, with the courier being close to a young lady Winterbourne knew.
Step-by-step explanation:
Winterbourne's companions in his travels include his aunt, who had been established in Rome for several weeks prior to his arrival, and a courier. The courier was described as being particularly intimate ('the most intime') with a young lady Winterbourne was also acquainted with.
Additionally, the young lady had made connections with some 'third-rate Italians' that she spent time with socially ('rackets about with'), which was a subject of local gossip.
In Alexandre Dumas' "The Count of Monte Cristo," besides Maximilien Morrel, the Count is also accompanied by a Nubian slave named Ali.
Ali serves as the Count's loyal and skilled attendant, assisting him in various capacities. Ali is notable for his unwavering loyalty to the Count, and his character reflects the diverse and international nature of the Count's entourage.
The novel features a cast of characters from different backgrounds, each playing a role in the intricate plot of revenge and justice that unfolds throughout the story.
