The iconic details from Conan Doyle's original books remain – they live at the same address of 221b Baker Street, have the same names and, somewhere out there, Moriarty is waiting for them.
Steven Moffat says: "Conan Doyle's stories were never about frock coats and gas light; they're about brilliant detection, dreadful villains and blood-curdling crimes – and frankly, to hell with the crinoline. Other detectives have cases, Sherlock Holmes has adventures, and that's what matters."This three part series starts on 25 July
