Pygmy

“Being a seasoned Londoner, Martin gave the body the 'London once-over' - a quick glance to determine whether this was a drunk, a crazy or a human being in distress. The fact that it was entirely possible for someone to be all three simultaneously is why good-Samaritanism in London is considered an extreme sport - like base-jumping or crocodile wrestling.”
― Ben Aaronovitch, Rivers of London
