What is the author's style in The Ox-Bow Incident by Walter Van Tilburg Clark?

The language is English. The words are a combination of a more formal language mixed with the more casual slang that men might have spoken at the time in which the novel is set. There are few foreign phrases in the novel, but there is a character who speaks Spanish so his language is often broken and he uses a grammar that does not compliment the English he is attempting to speak.
