One of my all time favorite authors is Dick Francis. When he passed away his son Felix, who had helped him on several books, took over writing mysteries about horse racing in England. This book centers around Mark Shillingford a race caller and television presenter. His twin sister Clare is a successful jockey. Mark suspects Clare is guilty of intentional losing several races. They have an argument about it but later that evening Clare is found dead after falling out of a hotel balcony window. The police believe it is suicide but Mark is positive it isn’t. He tries to find out the truth and because of that his life is threatened. As usual with all of the Dick Francis books I couldn’t put it down. Felix has done a wonderful job of continuing these thrillers and I can’t wait to read the next one.
