On Christmas Day, Edgeworth is arrested on suspicion of shooting a man on Gourd Lake. Despite being warned by Edgeworth to stay away from the case, Phoenix and Maya investigate Gourd Lake, where Gumshoe begs Phoenix to defend Edgeworth; they also meet Larry, now a vendor at the lake, who reveals Edgeworth to be a former friend of his and Phoenix's. They then meet photographer Lotta Hart, who has been taking pictures of the lake using a sound-activated camera in the hopes of finding the fabled monster Gourdy. Lotta discovers she has photos taken during the murder, but decides to take them to the police instead of showing Phoenix. Later, Grossberg identifies the victim as Robert Hammond, a former lawyer in his firm who served as defense attorney for the DL-6 Incident, a 15-year old case surrounding the death of Edgeworth's father, Gregory. Phoenix once again approaches Edgeworth, deciding to take his defense in order to both prove his innocence and solve the mystery surrounding the DL-6 Incident. Edgeworth accepts Phoenix's offer, revealing that the prosecutor will be his undefeated mentor, Manfred von Karma.
