I like the alliteration here. It makes the image of long and lifeless stronger. On which the ogre's ace begins chop chop. I really don't like the repetition here. It seems rather silly, as, actually does the word ogre.
Ogres live in dark castles.
Perhaps, though, the writer is hoping the reader identifies ogres with butchers who chop up once living creatures. I see the hub bub of a metropolitan street. I remember the butcher's shop I passed when I walked home from my job in a London hospital. People always on the street. How odd that the butcher's is a separate place from the green grocer, etc.
