It's entirely unintentional, but it looks like there's a theme developing here. There's some essential Rat and Mouse viewing tonight at 9pm on BBC1, when Whistleblower goes undercover at a number of London estate agencies. Apparently, we'll be able to sit back and enjoy agents artificially boosting prices by lying to surveyors about the actual value of deals; faking signatures; making false low offers to bring down clients' asking prices after winning the very same clients by suggesting they can achieve a much higher price; flyboarding; and - my own favourite because I believe I was once the target for this myself and even the thought of it puts me in a Silence Of The Estate Agents kind of mood - undervaluing a property in order to sell it off cheap to a property developer in return for a backhander. Don't miss it.
