How does Lilian Jackson Braun use imagery in The Cat Who Turned on and Off?

Examples of Imagery:

"Between paragraphs...a pair of piercing eyes kept boring into his consciousness. He knew that kind of stare. It indicated one of two things. The elegant Miss Duckworth was either myopic-or frightened" (pg. 44.)

"... [Qwilleran] touched his moustache gingerly. There was an odd feeling in the roots of it - a tingling sensation he had experienced several times before, It always happened when there was murder in the air." p. 46
