Here are a few of my favorites:
From The Big Sleep
"A few locks of dry, white hair clung to his scalp, like wild flowers fighting for life on a bare rock."
" The old man licked his lips watching me, over and over again, drawing one lip slowly across the other with a funereal absorption, like an undertaker dry-washing his hands."
"The General spoke again, slowly, using his strength as carefully as an out-of-work showgirl uses her last good pair of stockings."
"He looked a lot more like a dead man than most dead men look."
From: The Lady in the Lake
"The little blonde at the PBX cocked a shell-like ear and smiled a small fluffy smile. She looked playful and eager, but not quite sure of herself, like a new kitten in a house where they don't care much about kittens."
"Grayson put his bony hand out and I shook it. It felt like shaking hands with a towel rack."
"A wizened waiter with evil eyes and a face like a gnawed bone ..."
"She put a firm brown hand out and I shook it. Clamping bobbie pins into fat blondes had given her a grip like a pair of iceman's tongs."
"We shook hands. He had a hand like a wood rasp."
