Rupert Everett and Ian Hart take on the roles of Sherlock Holmes and Dr. Watson in this grisly whodunit set in Edwardian England, where the murder of a working-class girl unexpectedly turns up ties to London's high society. When a link to the upper-crust Lady Alice Burnham (Helen McCrory) is uncovered, it's time for a little sleuthing from the famed detective. Relying on his usual elementary logic, Holmes works to crack the case.
