For the last few months, I've been mistakenly included in the email list of some policewoman from Manchester. She has the same surname as me, and her husband has the exact same name as me. I assume the husband's also getting the emails because there's another address in the list that's a small variant on my own - in any case, she's never asked why he hasn't answered. I got one today that says she moving to a new department, so there's a chance she might start a new email list from scratch and I'll be out of the loop. My question to the panel is this: should I have some fun with this before she goes? Should I cause some marital discord by confessing to an affair, or hinting at some criminal skullduggery?
