Up here, anything can happen.
Even murder. . .
The Heights is a tall, slender apartment building among the warehouses of Tower Bridge, its roof terrace so discreet you wouldn't know it existed if you weren't standing at the window of the flat directly opposite. But you are. And that's when you see a man up there - a man you'd recognize anywhere. He's older now and his appearance has subtly changed, but it's definitely him.
Which makes no sense at all since you know he has been dead for over two years.
You know this for a fact.
Because you're the one who killed him.
