What is an example of imagery in the novel, Murder on the Orient Express?

Imagery:

"By the step leading up into the sleeping-car stood a young French lieutenant, resplendent in uniform, conversing with a small man muffled up to the ears of whom nothing was visible but a pink-tipped nose and the two points of an upward-curled moustache."

"...a little man with an enormous mustache...She had never seen anyone quite so heavily muffed...What an egg-shaped head he had."

"You saw her? Was she old—young?"
"Didn't see her. Wasn't looking that way. Just a rustle and a sort of smell of scent."
"Scent? A good scent?"
"Well, rather fruity, if you know what I mean. I mean you'd smell it a hundred yards away."
