This story appears to take place in Victorian London (to me) which is a bit of cliche (IMO). But I love its celebration of the urban.
A little boy finds a scarf. So, instead of cleaning people's shoes like he is supposed to be doing, he spends the afternoon looking the scarf's owner in one of the apartments on either side of the street where he found it. It's cool (but totally unrealistic) how he scales between the buildings along the laundry lines. He meets people with a broad rang of backgrounds (Italian, Polish, Yiddish, Jamaican, Chinese, Ukrainian....), and finally finds the scarfs owner on the roof.
