Built out of words, it is the engine that drives the plot of his book and also the movie, in which another object is created: a prop that has to represent the thing that Hammett created out of words, inspired by the Kniphausen Hawk, and this represents the falcon in the movie.
Bygget ud af ord, det er motoren, der driver bogens og også filmens plot, hvor endnu en genstand er skabt: en genstand, som skal repræsentere den ting, Hammett skabte ud af ord, inspireret af Kniphause-høgen, og dette repræsenterer falken i filmen.
