Night of Fire is Colin Thubron’s first novel for 14 years. For most of us he is better known as a travel writer, perhaps the finest of our time. But between journeys there have been seven previous novels, and this new one draws on his travelling. Ostensibly confined to a house converted into single apartments, and a night when it is consumed by a fire starting in its basement, it actually, in its chapters each devoted to one of its seven characters, wanders the world, while also moving to and fro in time.
