Eddie Mars—Arthur Geiger

Eddie Mars—Arthur Geiger is a relationship of calculated alliance: Mars protects and uses Geiger, while Geiger’s independent blackmail operation gives Mars a means to test the Sternwood family for weaknesses. The arrangement links a local extortion scheme to Mars’s broader effort to control what the authorities learn about the family and Rusty Regan’s disappearance.

Geiger’s Blackmail Scheme

Geiger tried to blackmail General Guy Sternwood using legally valid promissory notes, though Mars explains that Geiger would not have dared sue on them. Geiger presented the notes in a way that tested whether their owners were frightened enough to pay. If he found a promising target, he pursued the threat; if not, he abandoned it. Mars describes this as Geiger’s own idea, not an operation devised by Mars, and says Geiger used the tactic on multiple people.

That distinction establishes the limits of their alliance. Geiger developed and operated the scheme himself, but his leverage and access served Mars’s purposes. The General’s decision to hire Philip Marlowe rather than simply pay Geiger also mattered: as Marlowe later reconstructs it, Mars wanted to find out whether the General was vulnerable to blackmail and whether Geiger’s pressure could produce money.

Protection and Leverage

Marlowe’s explanation to Vivian Regan casts Mars as Geiger’s backer and Geiger as a cat’s-paw. Mars could benefit if the General paid, but he also had a longer-term financial interest in Vivian: if the General was not afraid, Mars could wait until she inherited and meanwhile take money from her at the roulette tables. Geiger’s scheme thus functioned as a test within Mars’s wider strategy, rather than as the whole strategy itself.

Mars’s relationship with Geiger was not founded on simple loyalty. He admits that knowing other people’s business is a bad investment in his circle, yet he knows the details of Geiger’s methods and their implications. He tells Marlowe that pursuing Geiger’s blackmail angle alone is a dead end, separating the dead blackmailer’s scheme from the deeper game Mars is playing.

Larger Consequences

The relationship becomes more consequential in Marlowe’s final reconstruction of the connected cases. He identifies Geiger’s attempt to blackmail the General, Joe Brody’s possession of the photographs, Mars’s gambling operation, and Lash Canino’s role as parts of an overlapping design. Geiger’s death at the hands of Owen Taylor did not end Mars’s larger plan; Marlowe argues that Mars was operating beyond what Geiger or Brody understood.

Geiger’s role therefore reveals both the usefulness and the limits of Mars’s protection. Mars could use Geiger’s blackmail attempt to probe the Sternwoods, but Geiger was not the principal architect of the larger concealment surrounding Regan. Their connection helps explain how Mars turns other people’s secrets and criminal ventures into leverage, while keeping his own objectives distinct from theirs.
