The Library of St. John the Beheaded contains the most dangerous books in all creation so when some of them are stolen who else should the Vatican call but Sherlock Holmes? Immediately, one of the possible suspects seems more suspicious than others. He has traceable background, refuses to give straight answers and hides behind a pseudonym. However, Holmes and his loyal friend Watson soon realise this suspect is also their greatest hope: war is brewing and an Old God is rising, to save humanity they need The Doctor as much as he needs them. Based on the original 1994 New Adventures vel by Andy Lane.Sylvester McCoy originally played the Doctor in 1987-1989, (then again in 1996) while his other work includes Radagast the Brown in Peter Jackson's epic The Hobbit films. Sophie Aldred's Ace companion is often viewed as Doctor Who's first contemporary young friend for the Doctor, setting out the template followed in later years by Rose Tyler (Billie Piper) and Clara Oswald (Jenna-Louise Coleman). Not only is this story an adaptation of a popular 1990s Doctor Who vel, but it features the Doctor teaming up with Sherlock Holmes - as played by Nicholas Briggs for Big Finish over the last five years!
