Today's obscure opus is The Track of the Cat by Walter Van Tilburg Clark
First published in 1949, this Gothic Western transforms the sweeping vistas of the great outdoors into a nightmare of cold, claustrophobic terror, as three brothers head out into a mountain snowstorm to hunt an elusive black panther.
Recommended by Robert R. McCammon in Horror: 100 Best Books as "A great horror novel - but, first and foremost, a great novel"......need I say more?
Trivia Tidbits: Van Tiburg Clark is also the author of The Ox-Bow Incident.
The Track of the Cat was adapted to film in 1954, starring Robert Mitchum, and shot almost entirely in black and white to capture the book's eerie atmosphere.
