I’d like to ask about a sentence in "His Last Bow" by Arthur Conan Doyle.
As to you, Watson, you are joining us with your old service, as I understand, so London won’t be out of your way.
I can’t exactly tell what the speaker Holmes means by the line above, especially about his use of the word “service”. It certainly isn’t about military service, is it? So what’s this? They are taking a man to the Scotland Yard here, so is this “service” old friends in the police force like Lestrade, Hopkins and some others? (I don’t think they were there though, for the setting of this episode is way later than when Holmes was an active consulting detective in London) . Or maybe this “service” doesn’t refer to any organization or society, but a quality of someone’s character or something? By this line, is Holmes’ saying something like “you were a good sport, my devoted assistant, friend-helping guy, so of course you’re coming along with me like a good sport, your old self right?” I don’t know. Could someone paraphrase this please?
