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.
