In attendance at the annual event is a murderer. Inside the main barn, jockey Nigel Danforth is stabbed to death. Adela Valiant, who was seeing the victim, is extremely agitated by Nigel's death. Her family is extremely elated by the murder of a man they believe to be a gold digger.
Drugs seem to be related to the jockey's murder.
In exchange for eyewitness information, a moratorium on game hunting of mice will occur. If that fails, well, Mrs. Murphy will just have to apprehend the criminal without human help. Mrs. Murphy is a great amateur detective, whose biggest problem is providing the case information to humans. Perhaps, a blind date can arranged between Mrs. Murphy and Midnight Louie because these two private investigators are top cats. Comments and suggestions welcome.
