Among the towering red cliffs of Petra, like some monstrous swollen Buddha, sat the corpse of Mrs Boynton. A tiny puncture mark on her wrist was the only sign of the fatal injection that had killed her. With only 24 hours available to solve the mystery, Hercule Poirot recalled a chance remark he’d overheard back in Jerusalem: ‘You see, don’t you, that she’s got to be killed?’ Mrs Boynton was, indeed, the most detestable woman he’d ever met.

Piranesi’s house is no ordinary building: its rooms are infinite, its corridors endless, its walls are lined with thousands upon thousands of statues, each one different from all the others. Within the labyrinth of halls an ocean is imprisoned; waves thunder up staircases, rooms are flooded in an instant. But Piranesi is not afraid; he understands the tides as he understands the pattern of the labyrinth itself. He lives to explore the house. There is one other person in the house—a man called The Other, who visits Piranesi twice a week and asks for help with research into A Great and Secret Knowledge. But as Piranesi explores, evidence emerges of another person, and a terrible truth begins to unravel, revealing a world beyond the one Piranesi has always known.
