The twins are in bed when it
happens: they hear a sound like
a wet cabbage hitting the wall, a
clattering on the roof tiles, then
a tapping at the window. It's a
girl with a broken wing - and
she's come to stay. Who is she?
Where has she come from? And
more importantly, what does
she want? Perhaps she's their
guardian angel ... but would an
angel snore and have filthy feet?
