An unwelcome development
Admittedly, the Editor's camera has an impressively powerful zoom facility which, combined with the cropping function from the associated software, manages to give the impression that this window is rather closer to Bracknell Towers than is actually the case. Nevertheless, the offending creatures are clearly visible from Lady Bracknell's back door.
Given that none of them has moved in the last twenty four hours, it is probably reasonably safe to assume that they are merely models of something long-leggedy and repellent. However, it would not do to be complacent: Lady Bracknell will be keeping a keen eye out for any suspicious behaviour.
