How does Elizabeth George use imagery in For the Sake of Elena?

Imagery:

"He began to weep-dry, hot, tear-less sobs for his daughter and his wives and the mess he'd made of every part of his life"

"She picked up the sandwich and took a hefty bite, chewing with a pleasure that seemed only marginally related to the food"

"He felt unaccountably touched by the unadorned melody and he marveled at the human heart's capacity to be moved by something as simple as sound."
