Dear Mary | 1 September 2016

Q. We have a heavenly house in Corfu where we go as often as possible. The best thing about it is the intelligent Corfiot couple who look after it for us. Everything is spotless, the cooking is perfect, and their competence make us the envy of all our local expat friends. Now someone has told me that when we are back in England, our couple host wild parties and sleep in the master bedroom. There has been no damage, but instinct tells me that what she says is true. I don’t want to humiliate the couple with a showdown because I don’t want to lose them. But how else can I stop the parties?

A. The parties would stop if you told the couple your insurance company has asked you to install live streaming security cameras linked to your laptops in England. But bear in mind this could backfire.
