Book excerpt: Eighteen years after the events of A Study in Red, young Jack Reid - nephew of Robert Cavendish - discovers the journal that previously belonged to his uncle. A troubled child with psychological issues, Jack's recent years have been relatively problem-free. But after discovering the mysterious journal, his personality changes overnight, and he soon leaves his home. Soon, a series of gruesome murders similar to the Whitechapel Murders of 1888 start taking place in the seaside resort of Brighton. Detective Inspector Mike Holland and Sergeant George Wright are pulled into a case that will tax their investigative skills to the limit. Who is the man in the strange old house on Abbotsford Road, and does he have a connection to the young Jack Reid? And what is the truth behind the riddle in the Legacy of The Ripper?
