For the best part of a month a huge rhinoceros has been squatting in my studio. The beast takes up most of the downstairs floor. The dog refuses to cross the threshold and if I’m ever to get started on the drawings for my imminent exhibition, The Gilded Desert (And Other Allegories of the Beau-Monde), then someone has to be off “on safari” very soon.

The African savannah is anything but “gilded” for the rhino nowadays, judging by the work of Tusk, the conservation charity for whom I am decorating one of 21 rhino sculptures that will appear across London in the autumn.
