Tristan and Izzy are on the brink of marital breakdown. Sex has become less than perfunctory and distance shadows their interactions. The arrival of their new neighbour may just be their salvation: or, will she be their undoing?

Vivacious, enigmatic and enticing, Viv piques both Tristan and Izzy’s interest, her appearance in their lives offering them diversion from their faltering marriage and a window into the people they might be were it not for each other.

But as Viv becomes an ever-increasing presence in their lives, the couple are forced to confront the long-ignored truths about themselves, each other and their pasts that have been a silent, spectral presence between them for years. At this fork in their marriage, they will face the most difficult decision: to cleave together for the sake of their union, or to walk away.

A story about how the ripples in a relationship can become waves, The Single Neighbour holds a mirror up to the promise of domestic bliss, and asks whether an extinguished spark can ever be relit.
