The Night It Rained Bullets by Brian Wynne (Brian Garfield)
My rating: 4 of 5 stars
Prolific and talented author Brian Garfield, writing as Brian Wynne, wrote several Westerns taking place in the fictional town of Spanish Flat starring hard-boiled Marshal Jeremy Six. Here the town is invaded by three exceedingly psychotic and brutal outlaws during a winter snowstorm, The arrival of a gambler with a gunslinger reputation, and a drunken rich gambling troublemaker add to the explosive situation which soon escalates out of control resulting in Six having to make some hard decisions and resort to some serious violence. I tend to like stories that take place in confined locations due to conditions that the characters don’t have control of, storms, hurricanes, etc. Tarantino’s Hateful Eight comes to mind. A single day compressed timeline ramps up the tension to a blistering pace making this difficult to put down. A fine novel and an easy four stars.
Here's scan of it. (if you don't mind reading yellowed images in a comic reader)
