A Study in Pink is a case featured in Criminal Case as the fifty-second case of Mysteries of the Past (Season 4) and the two-hundred twenty-third case overall. It takes place in the Ivory Hill district of Concordia.
Upon receiving a report of a murder, Isaac and the player went to the Pistols & Petticoats office to collect the body of editor-in-chief Barbara Coldwell, who had been pushed out of the first floor office window onto the stairs.
Mid-investigation, Evie, who wrote for Pistols & Petticoats, confessed that Barbara was in her office on the airship the morning before the murder, forcing the team to flag her as a suspect. Later, artist Callum Edwards asked to be locked up because he believed he was "cursed" after being suspected of two murders. The team then found enough evidence to arrest Barbara's daughter, Verushka Coldwell, for the murder.
Upon admitting to the murder, Verushka complained that her mother always controlled her. When she thought of marrying Callum (despite him not knowing about it yet), her mother said she was not allowed to marry until she was 25 years old. Angry, she pushed her mother out of the window of the Pistols & Petticoats office, killing her. Judge Takakura sentenced her to 25 years in prison.
Post-trial, Viola and the player talked to Katherine Woolf to ask for help in bringing down Malcolm Rochester's reputation. According to Katherine, Barbara might have known something regarding Malcolm because she based her stories on real political scandals. The three then went to her office and found Barbara's notebook, which (per Evie) seemed to suggest that Leopold Rochester knew something immoral about Malcolm. Upon interrogation, Leopold said that Malcolm was fond of visiting prostitutes. He directed the three to the Pistols & Petticoats office for photographic evidence. Upon finding the photo there, Katherine and the player first taunted Malcolm with the photo before Katherine went on to write the article.
Meanwhile, Rose designed a body armor that the Squad could use in case of another assassination attempt and tested it successfully on Dick. After all the events, Chief Wright told the team that the backlash from the article Katherine published had the disgraced Malcolm resign from his position and had the anti-free press bill removed from legislation. Furthermore, Maddie informed the team that she and Charlie were engaged. The team then stayed on the lookout for any more of the Rochesters' plans.
