At the Narrow End of Time — Steve Lee

"Somewhere in the North End of London, a clueless janitor desperately tries his hand at breaking into the netherworld of the modern pulp fiction industry. Prone to perpetual daydreaming and lost in delusions of grandeur, this would-be author pounds out reams of melodramatic drivel, shaped by the formulaic style of his quintessential washed-up agent from hell. Yet despite his best efforts, the only organizations interested in his ""gift"", turn out to be a number of very... ""clandestine"" groups, who aren't exactly focused on publishing manuscripts. Of these groups however, one is completely unlike any other organization on the planet.
Through a few ""cat and mouse"" games, this unique group begins to attract some unwanted attention of its own. Yet even as it is about to be exposed, it simply erases itself from the memory of everyone â€" save one man... As things suddenly begin slipping sideways across tangents in time.
Through it all, this lone odd-man-out finds time ... is not quite what we thought it was."
