The novel “The Twilight Streets” by Gary Russell was published for the first time in 2008.

People prefer to avoid the Tretarri district in Cardiff even if nobody understands exactly why. The houses are now old and shabby because nobody wants to live there even if there’s no crime, simply they all try to move as soon as possible and eventually the area fell into decline.

A new project aims to renovate the district and a company is running the task. It’s not just about building modern houses and ensuring adequate services to the population, there are also performances and parties in the streets to mark the new course. When Bilis Manger’s presence is discovered, Captain Jack Harkness and his team start investigating, a job made more complex by the fact that if Jack tries to get close to the area he feels too sick to enter.
