In paragraph 3 of ch. 16 what atmosphere is created? What contrast do you see ?

"The river wound in and out in its pretty delicate curves, looking like a silver serpent beneath the glittering rays of the moon. Long shadows from overhanging trees spread occasional deep palls right across the road. The bays were rushing along at breakneck speed, held but slightly back by Sir Percy's strong, unerring hands."

Our atmosphere in this paragraph is suspenseful and filled with action. Marguerite is enjoting her husband's company and attention. This contrasts with their all too often chilly relationship.
