Inspector G. Lestrade is an associate of Sherlock Holmes and Dr. Watson. A long-time veteran of the police force, he often seeks Holmes's help on difficult cases. His relationship with the amateur has changed significantly over time - initially antagonistic (with Holmes calling him "the pick of a bad lot"), it later developed into mutual respect ("We're not jealous of you at Scotland Yard. No, sir, we are very proud of you..."). He has a long rivalry with Tobias Gregson, the only other Yard inspector that Holmes considers reasonably capable.
