a fly on the wall(idiom): someone who can secretly see
and hear what happens
English illustrator Rory Dobner lives and works in beautiful Hampstead. Gambling addict foxes, gun-toting octopuses, cupcake-eating lizards, traveling mouses with umbrella, smoking fish, geyhounds with shabby top hats and chains, crowned bees are just a few of the quirky characters he is turning out of his whimsical imaginative world. No wonder he answered he would be a Victorian magician - when asked by Life.style.etc what he would be in another life.
