Final answer:
In Charles Dickens' novel 'A Tale of Two Cities', Dr. Manette's servant before he was sent to prison was Roger Cly, who is also involved in espionage.
Step-by-step explanation:
The person who worked for Dr. Manette before he was sent to prison is Roger Cly. Dr. Manette is a character in Charles Dickens' novel A Tale of Two Cities, and Roger Cly was his servant. However, Cly is also involved in espionage and acts as a spy, which contributes to the complex plot of betrayal and revolution that unfolds in the story.
Before imprisonment in "A Tale of Two Cities," Dr. Manette employed a devoted manservant named Defarge. This loyal assistant played a pivotal role in the narrative, witnessing Dr. Manette's suffering during his unjust incarceration. Later in the story, Defarge and his wife, Madame Defarge, become significant figures in the unfolding drama, adding layers of complexity to the intertwined fates of the characters.
Defarge's unwavering support and involvement in the revolution highlight the intricate connections between personal histories and the broader socio-political context in Dickens' masterful narrative.
Therefore answer is D. Roger Cly.
