Mr Owl is not an owl like any other. He lives amongst humans, in the London of the 1910's. He does not only hunt mice, he also has a desk job and flirts with charming women. When he's told that he's fly and a strange bird, he only nods proudly and politely. No plot twist in this story, only some depiction of what your daily life is like when you're an owl in a human's world.
