When Chen Ke and Jacob left Sean's estate, the guards in the courtyard still hadn't woken up.
The two of them weaved through the shadows of the buildings, stealthily moving through the blind spots where the gas lamps could not reach, and quickly hid in a pitch-black alley.
"Baron Mox, Lady Katherine, who are they?" Chen Ke asked.
"Mox is the best doctor in Langdon, seeing him for treatment costs a fortune, but his excellent medical skills obviously couldn't cure his own wife," Jacob said.
"You mean to say, Lady Katherine has passed away?" Chen Ke wondered. If this woman had died, Sean's earlier words carried some significance.
"No, no... she hasn't, Lady Katherine has a kind of neurological illness, Baron Mox tried many methods but couldn't cure her, and Lady Katherine hasn't left the house in years," Jacob said.
Neurological illness was still a very difficult condition to treat in modern times, much like a terminal illness in the 19th century.
