The listing, The Face of Fear by Dean Koontz 1977 PB has ended.
Graham Harris was once one of the world's foremost mountain climbers, until a fall five years earlier left him with a lame leg, a fear of heights...and a frightening psychic ability in which he can see murders as they are happening. Harris lives in New York City, where a murderous madman known as the Butcher has been mutilating young women. While he is giving an interview on live television one night, Graham senses the Butcher claiming another victim. When the madman realizes that [Graham] poses a threat to him he formulates a plan to kill the clairvoyant. While working late one night in his office building, Graham senses that the Butcher is coming to his floor aboard an elevator. With his girlfriend Connie at his side, Graham begins a long night of playing hide and seek to try and avoid the psychopath's grip.
