Rooftop shadows hide more than storms.

Only fools would be out on a rooftop on a wild, stormy night... and those with nefarious intentions. All Riley wants is to stay out of the weather, and stay out of trouble, but trouble comes looking for him.

The Skywalkers often emerge when the city shuts down for other folk. They are the ones who live above everyone else and keep the city and its buildings running. They are a loose-knit group who support and look out for each other.

When a possible murder disrupts the predictable pattern of his life, Riley finds himself at the centre of unwanted attention. More than that, it seems his life is also at risk. Where are the Skywalkers when he needs them?

A heritage consultant, a ginger cat, and a retired concert pianist with a past all play a role in Riley's desperate attempts to understand who is framing him, and why. From a high vantage point, it seems he may end up as another stain on the footpath.
