Many thanks to the twenty or so readers who took the trouble to tell me what they thought of my first flash story. I know it's not a popular genre, but I reckoned I'd give myself the challenge of trying one.
A couple of people thought that my characters should have taken a slower revenge within the law rather than burying the cheaters under the compost heap; I'll give that a go, but I suspect it won't qualify as a flash story - but that's another challenge.
