END OF THE LINE Farrel and Saunders, two railway cops, couldn't be more different. Farrel, the older bull, remembers the Lobo Tunnel wreck all too well. Saunders, young and inexperienced, figures that there is nothing left to learn about the six-year-old case. But their boss figures otherwise, and sends them out to dig up new evidence. Which is how they find themselves chasing down some of the accident victims who benefited the most. There's the blind physicist-did he really lose his sight in the wreck? And the crippled ballerina-she and her husband built a ranch with their settlement money, but did she really lose the use of her legs? And the former train conductor-why, after all this time, is he sending his teenage daughter on crazy wild-goose-chases to collect on an old debt? Saunders figures that they're chasing old leads for nothing, but Farrel has always thought that something didn't add up here. And now they're in a small desert town at the end of the line-on an old trail that leads right back to the beginning.
