Original Description
"On any given day we're lied to from 10 to 200 times, and the clues to detect those lie can be subtle and counter-intuitive. Pamela Meyer, author of Liespotting, shows the manners and "hotspots" used by those trained to recognize deception -- and she argues honesty is a value worth preserving."
