Sid Haley and his bionic arm track down the murderer of a jockey and a trainer, with the help of his cancer research chemist girlfriend and some DNA. What I like about Francis is you learn interesting technical stuff without being clobbered by it.
Sid Halley, the ex-jockey with the "bionic hand", is called upon to solve several complicated plots: His ex-wife and a charity; who is causing horses to get heart attacks; fradulent horse syndicates.
Film director Thomas Lyon is trying to film a movie based on a book about a local suicide, but some one keeps trying to knife people. Excellent story, tears at the end.
