Bio

Detective Inspector Greg Lestrade is an inspector with New Scotland Yard. He often requires Sherlock Holmes' assistance to help with difficult cases. Greg has been affiliated with Sherlock for the better part of five years, but he still does not know everything about the consultant's antics and is therefore frequently surprised at his actions.

Greg has respect for Sherlock and seems to possess none of the animosity his team has. He tries to get his team to cooperate with Sherlock whenever possible, even when Sherlock is being insulting. Despite this, he is often frustrated by Sherlock's cryptic deductions and lack of explanations for his conclusions, as well as his constant insults.

Greg seems to like Dr John Watson and it takes a lot more time for him to warm up to Sherlock. Greg becomes closer to Sherlock and John after seeing their friendship strengthen, even attending a small Christmas party at 221B Baker Street. He comes to Dartmoor where Sherlock and John are investigating sightings of a gigantic hound. He pretends to be there on holiday but Sherlock quickly deduces that he is there to help with the case; it is suggested but never confirmed that he was sent there by Mycroft Holmes. John tells Greg that Sherlock was secretly happy to see him, which pleases him somewhat. He later assists with the confrontation with Dr Bob Frankland in the Hollow.

When Jim Moriarty claims he will kill anyone Sherlock cares about, Greg is one of the three people Moriarty has identified as a friend of Sherlock's and therefore is a target. During the episode, Greg does everything he can to help Sherlock and ignores the doubts planted by Moriarty. Sally Donovan forces him to consider Sherlock's implication in the crime and to present the case to the Chief Superintendent. He later phones John to warn him of Sherlock's imminent arrest, an act that could have gotten him fired or even thrown in jail.
