YY to the idea that Rob will tell Miranda; I can hear him now:
'I must say Miranda, Justin's very lucky to have a wife like you who understand a chap has needs' [Beavis & Butthead huh huh style laugh]'
'what do I mean, well you know, a powerful man like him, forced to work away from his wife most of the week, has to have an outlet for his engergies...'
... and so on as we all wishe yet again Helen had pierced a bloody artery and been done with it!
I fear that the land thing may be a long term plot being set up with potential financial ruin on the horizon for Adam, Debbie, Kate and Alice and Ruari - it's all very easy to take out a £1.6m loan when you're in your 70s and it's all being agreed over some agreeable brandies and cigars; less fun when the land turns out to be crap and there isn't enough money to sustain the myriad offspring.
