I think this is fairly an easy one :P . In it Blair is a jockey living with Simon and Joel who adopted him. Jim an actor shooting in a location provided by Simon. I forgot who Jim's movie director or agent was. Blair and Jim met at the filming location. Halfway through the story, somebody sabotaged the racing horse. Or was it somebody dead? They were going to investigate. PLease help me. I read it only halfway and I want to finish it.
