How does Harlan Coben use imagery in Back Spin?

Imagery:

"Myron spotted Win at a corner table with six chairs. He sat alone. His expression was both glacial and serene, his body completely at ease. A mountain lion patiently waiting for prey."

"'A mother's guilt, the worst kind there is. The pangs are constant and ceaseless. They haunt your sleep. They point accusatory fingers. Every joyous swing of the golf club made me feel like I was forsaking my own child."
