What is the author's style in A Savage Place: A Spenser Novel by Robert B. Parker?

Although Spenser is an intelligent man who likes to read biographies about eighteenth century poets and F. Scott Fitzgerald novels, he is still a private detective who deals with the dregs of society and therefore tends to speak accordingly. Spenser's language, while not vulgar, tends to include some street slang as well as simple language in order to help those who are less educated understand him. Spenser also has a quirky sense of humor with which he occasionally makes up words in order to entertain those around him. Other characters also tend to use simpler words, such as Candy Sloan who speaks in simple sentence structure in order to make her words clearly understood by the audience of her news show and the people with whom she works.
