The particular house to which we were directed was a large, old-fashioned, Early Georgian edifice, with a flat brick face broken only by two deep bay windows on the ground floor. It was on this ground floor that our client lived, and, indeed, the low windows proved to be the front of the huge room in which he spent his waking hours. Holmes pointed as we passed to the small brass plate which bore the curious name.
