'In 1917, at the height of World War I, a fire destroyed the Greek city of Salonika (Thessaloniki), a staging post for Allied troops. The centre of an ‘Ottoman polyglot culture’, Salonika was at the time home to large numbers of refugees, many of them Jewish and Roma. It was in one of the refugee hovels that the fire started, an ember from a makeshift stove igniting a bundle of straw. From that single ember grew an inferno that burned for thirty-two hours, obliterating three-quarters of the city and leaving 70,000 people – by some estimates half the population – homeless.'
