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, turned into 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 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. Praise for The Turnglass, the Sunday Times top ten bestseller:‘This is a story about stories and their perspectives, the passage of time and the slow march of the inevitable.
