In Bolt, Dick Francis continues the misadventures of Kit Fielding, jockey and all-round good guy. Francis' heroes are nearly always good and honest and brave, but never boring. They're the sort of men women would love to love and men should want to be like.
This time, however, Kit seems on the verge of losing, Danielle, his fiance and the love of his life. As he wrestles with these feelings, he is struck with the murder of the Princess' horses, first one, then two, then one more. Henri Nonterre is out to make the Princess and her husband turn to gun manufacturing, but Kit will do anything in his power to keep that from happening, as long as the family chooses to resist.
Meantime, Kit's old enemy, Maynard Allerdeck, looms in the background with renewed malice. What can possibly have increased his hatred for this particular Fielding? Fully occupied in helping the Princess and her family (which includes Danielle)avoid Nonterre's machinations, Kit merely tries to avoid any adverse contact with Maynard. But that may not be possible.
In typically honest, straight forward fashion, Kit strives to protect his employers and friends, and the horses he loves so much. In the meantime, he waits for Danielle to make up her mind about whether she wants to spend the rest of her life with him. A first rate story and most pleasant narrator.
