At the bottom of our garden

I’ve had a feeling, for a few days now, that we are being watched.
Nothing concrete.
Until now.
My wife has poo-pooed the idea and suggested that my imagination has gone into overdrive after reading the latest Rebus detective story.
However, now I have incontrovertible evidence.
Not only are we being watched, our phone line is also being tapped!
I have no idea why this should be happening.
But, I have been extremely critical of the present Prime Minister and his cronies, so perhaps he has instructed Special Branch to gather some evidence!!!
