I seem to recall brandy being request after an ordeal but i can't rem. the episode or what took place. I also rem. it being the drink of chioce in Sherlock Holmes to calm the nerves after a fright.
I'm afraid I don't know, but I do know that at the climax of "Missing Melody," Higgins did say something like: "It's early, but I'm going home for a drink... the sun must be setting somewhere in the world".
