i think sudden fear is a very good example of the so called films noirs and also joan crawfords performace is very convincing as the frightned woman who tries to save her life as well as she can
Positive

This one doesn't really fall into the Western category, but it's full of hammering action, informative local California history, and mystic goings-on. Seacoast adventures, early Califronia ranching, great good-guys and really bad bad-guys, and mysterious appearances by silent, unknown characters fill this one to the brim! Best of all, L'Amour introduces in this story, for what I believe was the first time in his writings, the famous "portal to the other side," which really sets this story apart from almost all of his other works. Excellent yarn through and through. You won't forget it for a long time after you first read it!
Positive

Nice pictures, but no descriptions and the map on the book doesn't even mention Merritt IslandBuy a proper birdbook rather than this overpriced pamphlet

Negative
