Marlowe drives Terry Lennox to Tijuana
Marlowe drives his drunk friend Terry Lennox to Tijuana without asking questions, and is then jailed for refusing to talk after Lennox's wife Sylvia, daughter of the tycoon Harlan Potter, is found murdered. Lennox's confession and apparent suicide in Mexico close the case fast, which is what Potter's money wants. Marlowe's loyalty is finally repaid with the discovery that Lennox faked his death, let his friend carry the risk, and had become a different man, so the friendship is ended by the person it protected.
