Four short year after the Golden Gate Bridge opened in 1937, this detective flick was produced in San Francisco. Humphrey Bogart plays a private detective. He is retained by a beautiful women, who under false pretenses has Bogart’s partner shadow a man, who allegedly has let her sister to run away with him to San Francisco. Before we know it, two people are dead. The plot turns fast. While the themes of the film (greed, love, passion) are eternal, the film did not age as well as the Golden Gate Bridge, which is celebrating its 75th anniversary this year.  I had more fun with African Queen, another old Humphrey Bogart film. But the writing is very good.
