The Little Sister has always had it tough. The novel was released when the hard-boiled detective fiction was already on a downturn. Hollywood was moving away from it as well, so unlike all the previous Marlowe stories, it was not made into a film until twenty years later. At a time when Humphrey Bogart definitely wasn't available anymore. And it even lost its title, being called just Marlowe. Though make no mistake, don't even let the appearance of Bruce Lee on the cast list distract you – both the novel and the film are a little underrated.
