Realizing he was set up, Gittes assumes that Mulwray's husband is the real target. Before he can question him, Lieutenant Lou Escobar fishes Mulwray, drowned, from a freshwater reservoir. Under retainer to Mrs. Mulwray, Gittes investigates his suspicions of murder and notices that, although huge quantities of water are released from the reservoir every night, the land is almost dry. Gittes is warned off by Water Department Security Chief Claude Mulvihill and a henchman, who slashes Gittes's nose. Back at his office, Gittes receives a call from Ida Sessions, who identifies herself as the imposter Mrs. Mulwray. She is afraid to identify her employer, but tells Gittes to check the day's obituaries.
