Sherlock Holmes buffs have many things to look forward to this holiday season: the return of the famous detective to movie theaters and the chance to follow in his footsteps and those of his creator, Sir Arthur Conan Doyle, in the United Kingdom.
In honor of the December 16 release of Guy Ritchie’s “Sherlock Holmes:  A Game of Shadows” — featuring the stars of Ritchie’s previous Holmes film, Robert Downey, Jr. as the detective and Jude Law as Dr. John Watson — several hotels in London have created Holmes-related promotions.
The Langham, London — a landmark hotel at the top of Regent Street often visited by Conan Doyle — is offering several Holmes-related packages. The more deluxe of the two, priced at 595 pounds per night, includes one night in the Sir Arthur Conan Doyle Suite; breakfast for two; two tickets to a Sherlock Holmes walking tour, with a guide from London Walks, the walking tour company; and the book, “The Adventures of Sherlock Holmes,” one of whose short stories mentions the Langham. The package is also being offered for 265 pounds per night with accommodations in a standard double room; both packages are available through March 31.
Meanwhile, through January 31, the Park Plaza Sherlock Holmes, a boutique hotel near Holmes’ residence on Baker Street, is offering a “Sherlock Scones”  afternoon tea, including two scones decorated with a profile of the detective, tea or coffee, priced at 6.95 pounds. Guests also receive a quiz with Holmes-related questions and can borrow a magnifying glass to help find answers.
Also in London, every Friday afternoon London Walks offers a “In the Footsteps of Sherlock Holmes” tour, which visits Charing Cross, the Strand and Covent Garden, sights once favored by the detective. Another must-see: The Sherlock Holmes Museum, at 221b Baker Street, whose study overlooking Baker Street is maintained as it was in Victorian times.

Dartmoor, a region of wild, open country in southwest England, is home to many sights that inspired Conan Doyle and his Holmes tales, like the tors, or rocky hills, of Believer and Vixen, and the Foxtor mires, or bogs.

A special, permanent exhibit at the Surgeons’ Hall Museum in Edinburgh, Scotland, where Conan Doyle was born in 1859 and studied medicine at the University of Edinburgh, is devoted to the author and Joseph Bell, Doyle’s professor of clinical surgery. Bell taught Conan Doyle the importance of detailed personal observation of medical patients, a skill famously attributed to Holmes. The exhibit contains letters, anatomical specimens, artwork and other objects that trace the family and professional backgrounds of Conan Doyle and Bell.
