And the fire had power, that he had learned early on, power to exhilarate, power to transform, power to induce wonder and terror. He had first read about the great Tooley Street fire of 1861 in school, which seemed to him now an odd place to have discovered a life’s calling.

The conflagration had burned for two days and consumed over three hundred yards of wharf and warehouse, damage unequaled since the Great Fire of 1666, damage not to be seen again until the Blitz.

There had been other fires, of course: the Mustard Mills in 1814, Topping’s Wharf in 1843, Bankside in 1855; it seemed to him that fire was as necessary to Southwark as birth and death, that it provided an essential means of growth and regeneration.

Heat began to sear his face; the skin across his cheekbones and forehead felt stretched, his nostrils began to sting from the smoke and escaping gas. The blaze was well under way now, burrowing deep into the pile of furniture, then licking out in unexpected places. It was time for him to go, but still he lingered, unable to tear himself from the energy that gave him more than a sexual charge – it was a glimpse into the heart of life itself. If he gave himself up to it, let it consume him, would he at last know the truth?

But still, he resisted complete surrender. Shaking himself, he blinked against the stinging in his eyes and took a last look round, making sure he had left no trace. Satisfied, he slipped out the way he had come. He would watch from a distance as the fire mounted to its inevitable climax and then… then there would be other fires. There were always other fires.

Rose Kearny liked night duty best, when the station was quiet except for the muted murmur of voices in the staff room as everyone went about their assigned tasks. There was something comforting about the camaraderie inside held against the dark outside, and in the easing of the adrenaline rush after a call-out. And she considered herself lucky to have ended up at Southwark, the station where she had trained, and the most historic in the London Fire Brigade.
