Fan Casting Holmes VS Morgan

After solving the murderous cases that involved Jim Moriarty and him finally locked up, Sherlock Holmes feels bored yet again. He wants to solve another case really bad, and John Watson is just writing away on his blog about the case they did. Then, they get a call from Inspector Lestrade about a serial killer in Miami, Florida about the Bay Harbor Butcher. At first Sherlock thinks of this case as dull and repetitive, but he then learns that this serial killer kills other serial killers which peaks his interest. Catching a flight from London to Florida with Dr. John Watson, Sherlock arrives and starts looking for clues about the Bay Harbor Butcher. Hearing that the "World's Greatest Detective" is in America and helping with the BHB case, Dexter Morgan uses his wit and skills not only as a blood spatter analyst but also as the BHB to cover up his tracks and to distract Sherlock and Watson from ever solving this case. However, with Sherlock's keen eye for finding micro-details in evidence and Dr. Watson's skill as an army doctor, can Morgan really hide his identity from Holmes and Watson? Or will they come closer to finding out that there's more to this case that Holmes and Watson have to solve to get closer to the truth?
