In a world ruled by the Great Old Ones, a consulting detective is called to the grisly murder of the Queen's son...

I first read this in Smoke and Mirrors (I think) eons ago and remembered the bare bones of the plot but reading it in comic form was a great reading experience. Most of the cosmic horror is merely hinted at. I remembered who the detective was but forgot a lot of the particulars. Still a fun alt-history Victorian detective story. Rafael Albuquerque did a fantastic job on art.
