Samuel Spade’s jaw was long and bony, his chin a jutting v under the more flexible v of his mouth. His nostrils curved back to make another, smaller, v. His yellow-grey eyes were horizontal. The V motif was picked up again by thickish brows rising outward from twin creases above a hooked nose, and his pale brown hair grew down—from high flat temples—in a point on his forehead. He looked rather pleasantly like a blond Satan.
The above image and description of Daschiell Hammett's Sam Spade is from the website The Composites. The site is a collection of police composites of literary characters. They are made using descriptions of characters and law enforcement sketch software.
You can suggest a character for a future composite if you include a description of them from the source material.
