The woman who was bearing down on me was a good three inches taller and twenty pounds heavier than me and there was a mean look in her eyes. I tried to match her glare and circled her warily. She feinted a punch at me, but that opened up her defenses and I swung my leg up and round in a short, fast arc. It caught her in the ribs. Even through her body protector, it winded her. She crashed at my feet, and I felt the last of the day’s tensions flow out of me. It was a burglar who got me into Thai boxing three years ago. Dennis O’Brien is what I like to think of as an honest villain. Although he feeds and clothes his wife and kids with the proceeds of other people’s hard work, he’s got his own rigid moral code that he adheres to more firmly than most of the supposedly honest citizens I know. Dennis would never rob an old lady, never use shooters, and he only steals from people he thinks can afford to be robbed. He never indulges in mindless vandalism, and always tries to leave houses as tidy as possible.
