Mid-summer puzzles

A brief about the novel Mr. Satterthwaite did not know for certain what prompted him to maintain his relationship with Mr. and Mrs. Denman, for they were nothing like him; they did not belong from the roots to the developed world, nor did they belong to the interesting artistic circles, but they were materialistic, and above that, they were truly boring dull people. The first time Mr. Satterthwaite met them was in the French town of Biarritz, and he accepted their invitation to stay with them, then he went to them and became bored, and strangely he continued to go to them despite that.
