In Chapter 6 of Book the First in A Tale of Two
Cities by Charles Dickens, Lucie Manette  has traveled with Mr. Lorry to
France where her father, Dr. Manette, has recently been released from the Bastille. 
However, much psychological damage has occurred with the doctor.  For, he does not
really know where he is at the DeFarge's, nor does he remember having been a physician;
he believes that he is a shoemaker whose name is "One Hundred and Five, North Tower." 
When he is spoken to, Manette must be recalled from "the vacancy into which he always
sank." 

After DeFarge, the former servant of Dr. Manette
asks the former prisoner if he recognizes him to no avail, Lucie moves forward.  Dr.
Manette raises his head, and sees her "with a fearful look." With some trepidation, he
asks, "What is this!"  He wonders if Lucie is the gaoler's daughter.  Then, when she
replies that she is not, he asks, "Who are you?"

Lucie sits
beside him; he moves away, but she lays her hand upon his arm.  As her golden hair falls
over her neck, Manette slowly picks it up and looks at it.  But, his mind goes "astray,
and with another deep sigh, fell to work at his shoemaking."  However, Lucie puts her
hand upon his arm and he stares at it.  Finally, he pulls a scrap of folded rag attached
to a string which contains one or two golden hairs, and winds them around his finger. 
"How can it be!  When was it!  How was it!"

Manette finally
makes a connection with the golden hair that is his wife's and now that is Lucie's. 
Lucie holds her dear father's head upon her breast, rocking him and soothing him; her
love instills Manette with the power to recall his daughter. Thus, Lucie is defined as a
character who has a compassion for the unfortunate as she will treat Sydney Carton in a
similar fashion.  She is portrayed as inspiring love from the other characters, although
the reader does not perceive any real character development and must take this
inspiration on faith.  For the most part, Lucie Manette is a flat character, the typical
Victorian heroine with her fainting fits and unrelenting
earnestness.
