B.M. Bower 
The Quirt 

B.M. Bower was an American writer of Western novels and short stories who wrote over 55 novels. Several of her stories were subsequently adapted and made into movies. This story of the cow country concerns the efforts of the Sawtooth Cattle Company, who number their cattle by the tens of thousands, to eliminate the smaller outfits around. Al Woodruff, the evil eye of the Sawtooth, is efficient in his particular line of work, which is the reason why Brit Hunter of the Quirt ranch calls life in the Sawtooth country „extra hazardous”. Action and adventure there are a-plenty.
