A story about stories within stories, as four interconnected mysteries take the reader through the ages, from Shakespeare's day to a 19th-century Gothic former Priory, to 1920s Venice, and finally to 1940s California, from the internationally bestselling author of The Turnglass.

We begin with the last testament of William Shakespeare as he investigates the real-life murder mystery of his friend, playwright Christopher Marlowe.

The second story is a 19th-century Gothic tale about the discovery of Shakespeare's manuscript, set in an isolated former Priory, now a clinic for those who cannot sleep.

The third is a lighter Golden Age detective tale set in Venice, where private investigator Honora Feldman looks into a baffling case of theft and murder in the British expat community, with the Gothic story at its heart.

And finally, a 1940s American Noir, as Ken Kourian finds that a serial killer is recreating all the murders in The Waterfall, the companion book to his friend Oliver Tooke's The Turnglass.

The Waterfall is a beguiling and intricate mystery that cements Gareth Rubin's position as one of the most original authors writing today.
