‘Foyster proves to be not only a scrupulous and thorough historian, but also a delightfully inquisitive one…compelling.’

– Miranda Seymour, Literary Review

‘Foyster has turned a great mound of papers lying neglected in the Lambeth Palace Library into a grippingly readable tale.’

– Terry Eagleton, London Review of Books

'A highly engaging book that should reach a wide public'.

– Anne Crowther, Times Literary Supplement

‘A well-informed, sympathetic portrayal of an extraordinary world.’

– Guardian, Best History Books of 2016

‘Fascinating’.

– Spectator

‘Reveals an aristocratic household turned upside down by scandal and mental illness...Unputdownable.’

– John Guy, bestselling author of Elizabeth: The Forgotten Years

‘Thoroughly absorbing…heading beyond the immediate confines of its subject…the 3rd earl emerges…as a Georgian “character” to rank with Beau Brummell or Parson Woodforde’.

– DJ Taylor, Times

‘One of the early nineteenth century’s most notorious lunacy inquiries and a dynasty in turmoil...If this were a novel, no one would believe it.’

– Sarah Wise, author of Inconvenient People: Lunacy, Liberty and the Mad-Doctors in Victorian England

‘Extraordinary...A well researched and vividly readable account.’

– Catharine Arnold, author of Necropolis: London and Its Dead

‘Portsmouth’s story unfolds like a novel, filled with blackmail, abductions, adultery, secret marriages, disputed inheritances and family scandals. Readers will find the book difficult to put down. There’s also a Canadian postscript to the story: Portsmouth’s widow eventually immigrated to Canada and settled in Chatham-Kent where the story of “How the Countess of Portsmouth came to Chatham” remains a fixture of haunted walks in his Ontario town.’

– Dr Carolyn Harris, University of Toronto, royalhistorian.com

‘Foyster documents a family scandal ripped directly from early nineteenth-century headlines...The standing-room-only proceedings are exhaustively detailed, but equally as compelling are the stories of Wallop’s family, friends, and servants, who contributed, one way or another, to his cover-up, his exposure, and his downfall.’

– Booklist

‘Extensively researched and gracefully written.’

– New York Times Book Review

‘Highly readable and illuminates the world Portsmouth lived in. Cameos by the family of Jane Austen and Lord Byron are an added bonus.’

– Historical Novel Society

‘Ms. Foyster did a wonderful job taking all of the information from the case and putting it into chapter form to make it easier for the layperson to understand. She really makes you look at how those with mental disorders or disabilities were treated in Georgian England and makes you wonder if it is any different than today.’

– San Francisco Book Review
