Sherlock knows that as a small colt the world does not take him seriously. He has not yet come across his big break in crime solving. But when a certain fan of a certain book series gets out of hand its time for Holmes to get to work once more on cracking a case that will get people to pay him some mind.
The series of crime novels known as the Palesbrook Detective is a set of literary works that the young Holmes greatly enjoys. His passion for solving crimes came from the first time he picked up one of the writer's, a Mrs Windy Weather, books and has not been able to put them down since. But when the young detective chances across a murder scene with the fourth and latest instalment of the Palesbrook series in hoof he begins to notice some similarities between the gruesome murder before him and the murder of a certain insurance broker Don Richie in the first Palesbrook instalment. Holmes quickly notices the structure and the pattern of the murder before the police and decides that he needs to do something before the Palesbrook Madman re-enacts the entire series of horrible crimes with the residents of Canterlot.
