The popularity of the Sherlock TV series has provided a boost to Arthur Conan Doyle's classic detective novels. Fans of the books flock to the venue to explore the fusty, Victoriana-style three floors, which can typically be traversed in about 30 minutes. However, the long queues and high entrance cost cause many visitors to opt out of the experience, instead choosing to spend their time in the gift shop or getting a photo taken with the costume-wearing door guardian.
