ArtGumshoe is a story comic which begins with Nerva Scarlotte waking up lying in the back of an unfamiliar car with dried blood on her face and knuckles. It will eventually (after about four or five chapters) include the origins -- and then cases -- of the Easter and Barr Detective Agency; a/k/a, the Art Gumshoes.
But there's a large enough cognition gap between the end of Book 8 and the beginning of the events here that familiarity with the previous stuff isn't required. In fact, you'll know as much as most of the other characters if you go in without the backstories.
So, without furthermore ado, here's the first page of ArtGumshoe
