Princess Principal/Recap/S1/E07 Case 18 Rouge Morgue

Quoting from Wikipedia: "Dorothy is given a mission by Control to infiltrate London's morgue and recover a code cipher hidden in the body of a deceased Kingdom agent. Dorothy asks why she was chosen specifically, and it is revealed that the man tasked by the Duke of Normandy to find the agent's body is Danny MacBean, Dorothy's father. Dorothy (whose real name is revealed to be Daisy), has a tense reunion with her father, who has become an angry and unpleasant man due to the loss of his right hand. She confides to Beatrice that Danny used to be brilliant steam engineer before losing his hand in an accident, and began taking out his anger on everybody around him, including Dorothy, which caused her to run away from home. In a drunken stupor, Danny tells Dorothy how to find the body. She and Beatrice find the body and copy the cipher both so the Duke of Normandy won't be aware of its theft and so that Danny can pay off the loan sharks. While Danny goes to deliver the cipher, the loan sharks attempt to kidnap Dorothy and Beatrice but are easily defeated by Dorothy, and she finds out how far her father was willing to go to protect her from the loan sharks. Meanwhile, Danny attempts to negotiate more money from Gazelle to give to Dorothy, but is killed instead. As Danny's body is taken to the morgue, Dorothy and Beatrice wait for him at his favorite pub."
