Decision for Dusty Fog — J.T. Edson

Despite being on very good terms with Freddie Woods, Dusty Fog knew no more about her past than anybody else in the trail end town of Mulrooney. But with the coming of the British Railroad Commission to the town the secret of the beautiful and talented Freddie was disclosed. And as a result, she was threatened with extradition to stand trial for murder.
Dusty Fog had to face the decision of his life. As Town Marshal, should he arrest the woman he loved? Or should he betray his oath of office and prevent the course of justice?

J.T. Edson was a former British Army dog-handler who wrote more than 130 Western novels, accounting for some 27 million sales in paperback. Edson's works - produced on a word processor in an Edwardian semi at Melton Mowbray - contain clear, crisp action in the traditions of B-movies and Western television series. What they lack in psychological depth is made up for by at least twelve good fights per volume. Each portrays a vivid, idealized “West That Never Was”, at a pace that rarely slackens.
