We were three middle-aged men crossing a park at night. To our left were flats, around us a gloomy expanse of grass. We muttered angrily.
Our path led us past some derelict, steel-shuttered public conveniences surrounded by bushes, where a group of teenage boys was lurking. They stepped out, barring our way.
I aimed a karate kick at the first hooded youth but he must have been armed, perhaps with a baseball bat, as I felt a blow on my cheek . . . and awoke in shock, on the floor beside the bed.
