As Harold delves deeper into the case, he discovers a series of clues that seem to link the modern-day murder to Conan Doyle's investigation over a century earlier. Along the way, Harold encounters a variety of eccentric and colorful characters, including a brilliant but enigmatic researcher named Sarah, who helps him unravel the tangled web of clues and discover the truth behind the murder. "The Sherlockian" is a thrilling and inventive mystery that pays homage to one of literature's most iconic characters while also offering a fresh and original take on the genre.
