its not an idea its a build up concept with some plotting
basically its two defectives solving crimes (wow orginal) in a Victorian era type place with mythical and magical shit. The main character (Edwin gaylord) is a ghost and Bo (evil cinnamon) is a retired circus performer

ALSO!!!!
LT isn't a stand alone spirit. His kind can only be created through a fusion of an animal spirit and human soul. And the human soul was named Little Tommy (get it eyy) and he was a tiny skinny wreck

i love him he died from starvation bc he had extreme anorexia
which is ironic bc the tol LT borderline has a food addiction from his anxiety
