Claiming that people have seen Hollis with another woman, she asks Jake to investigate her husband’s alleged infidelity. 

One man accuses Hollis of being paid to steal water Jake then trails Hollis, who spends most of the day checking out the city’s water supplies. This event brings the real Mrs. Evelyn Mulwray into his office, where she threatens to sue Jake for ruining her husband’s name. Then the police have already discovered Hollis’s drowned body in the empty reservoir. Later, Jake investigates a dry riverbed where another drowning death occurred and meets a Mexican boy who tells Jake that he once reported to Hollis about the periodic flooding of the supposedly dry waterway. Jake nearly drowns when water comes coursing down the channel but manages to scramble to safety. He then comes across Mulvihill, who threatens Jake for trespassing. Mulvihill pins Jake’s arms back while an unnamed hoodlum slices Jake’s nostril open with a knife and warns him to stay off the case.

Later, Jake meets with Evelyn and accuses her of hiding something. He tells her that Hollis was murdered because he discovered that portions of the city’s water supply were being dumped Jake returns to Yelburton’s office. There, a secretary tells him that a man named Noah Cross once owned the city’s entire water supply, but his business partner Hollis Mulwray persuaded him to turn it over to the city. Jake accuses Yelburton of arranging both the pictures and Hollis’s death. Jake then returns to his own office, where Evelyn officially hires him to find out who killed her husband. Jake also reveals that he knows her father is Noah Cross, a revelation that makes Evelyn visibly nervous. Evelyn explains her nervousness by saying that her father and Hollis had a falling out over the Water Department, but she unintentionally hints that their disagreement may have had something to do with herself as well. 

Jake meets with Cross, who abruptly asks Jake if he has slept with Evelyn, which he has not. Cross then probes Jake for information, finally hiring him to find Hollis’s missing girlfriend. Jake tells Evelyn Mulwray what he has learned about this scheme, and the two discover that Cross and his associates at the Albacore Club, a private association of the wealthy and powerful, are hiding the scheme by purchasing the land in the name of the residents of a local rest home of which they are benefactors.
