Living Alone 

It’s 1915 and a witch on the run from the police stumbles in to a committee meeting and, by her mere presence, changes the life of everyone there. The story unfolds with dream-logic, full of humour, delightful characters (dragons, invisible mayors, fairy gardeners and a wizard), and unforgettable images including a mid-air WWI battle on broomsticks between the British witch and a German witch.
