If you are lucky enough to live in/visit Canada, or another country with shorter copyright periods (although Canada's may be going away with the sad renegotiation of NAFTA), then The Maltese Falcon and many (all?) other Dashiell Hammett titles are in the public domain, and you can get them for free from Faded Page, Gutenberg Canada, or other similar websites. If not, then you may be happy to see a legit (Vintage Crime/Black Lizard) version of The Maltese Falcon on sale in the US for only $1.99, which is the least it has been, according to eReaderIQ, in at least a decade. Hammett's titles are usually pretty expensive in the US, so I'd grab it now if you even think you might want it !

Spoiler:

A coolly glittering gem of detective fiction that has haunted three generations of readers, from one of the greatest mystery writers of all time.

A treasure worth killing for. Sam Spade, a slightly shopworn private eye with his own solitary code of ethics. A perfumed grafter named Joel Cairo, a fat man named Gutman, and Brigid O’Shaughnessy, a beautiful and treacherous woman whose loyalties shift at the drop of a dime. These are the ingredients of Dashiell Hammett's iconic, influential, and beloved The Maltese Falcon.
