Morland will be helping Sherlock and, given his background, will be using some of his contacts to do so. But he won't be a constant. "You'll see him and then he might disappear for a couple of episodes," said Noble.
"There will be stories in which Morland lends a hand with the investigation, but he's not a detective by trade," added Doherty. "He solves much, much bigger problems—global problems ... Sherlock enjoys people with resources, so we'll see him turn to Morland for help."
