It's a GIP! I've been icon-hunting while Mr Pedia reads the Holmes story and complains that I need to make my ACD/Watson voice more florid.

Check out artintheblood's Holmes & Wimsey icons. Nice, nice. The icons include this lovely one featuring the wonderful Eric Porter as Moriarty. Of course I am all about Porter's Soames Forsyte, Mr Sulky, but I also think his Moriarty was appropriately reptilian.
