Holmes goes to the window, his back stiff. He takes several deep, calming breaths. "Gentlemen," he turns back. His voice is calm but his jaw is set. "I propose a test. Really I think it'll be for the best." Another deep breath. "Do either of you speak Italian or French? If you do it won't be so much of a wrench, to converse with each other as people must do, without sounding as if we'd all gone cuckoo." Now that last is just too much! Holmes grinds his teeth in frustration.
