What is the author's style in The Day of the Triffids by John Wyndham?

There is a certain detachment to the novel's narrative language, a certain dispassion or coolness. This may be due to its essential Britishness - specifically, the almost stereotypical British reserve. In other words, passion in both narration and action in "...Triffids" is the exception, rather than the rule. In many narratives, such reserve might be considered evocative rather than shallow or limited, allowing the reader to fill in the emotional blanks of what's going on for him/herself.
