Elevator pitch / Linwood Barclay.

It begins on Monday, when four people board an elevator in Manhattan. Each presses the button for their floor, but the elevator climbs, non-stop, to the top where it pauses for a few seconds, before dropping. Right to the bottom of the shaft. It appears to be a horrific, random tragedy. But then, on Tuesday, it happens again. And when Wednesday brings yet another catastrophe, New York, one of the most vertical cities in the world, is plunged into chaos. Clearly, this is anything but random. This is a cold, calculated bid to terrorise the city. And it's working. But what do these deadly acts of sabotage have to do with the fingerless body found on the High Line? It will be a race against time to find the answers before a deadly Friday night showdown.
