Approaching Doon Mackichan’s doorstep, busy with its flower-filled plant pots, I am brandishing a bunch of roses and a packet of Dead Fly biscuits (AKA Garibaldi). From the doorstep, I hear her on the phone, to her agent as it turns out – how showbiz! She opens the door and I’m greeted by two large, very friendly grins: one from Doon, and the other from her elegant Staffordshire bull terrier, Stella, who wants to show me her ball.
