What is the author's tone in The Fencing Master by Arturo Perez-Reverte?

The author's tone varies over the course of ther novel. At times, it is clear and precise, just like successful and efficient fencing techniques. At other times it is vague and obscure, just like the uncertain political situation in the fall of 1868. And at other times the language captures the longing and loneliness of a man, his solitude, and his devotion to a dying art.
