Six packed suitcases. An elaborately iced cake. Two dozen dark red roses. A case of vintage champagne. All converging on the house know n as Foxes' Trot in the country of Surrey... and for the most innocent and pleasant of reasons. Lady Balaclava's three daughters and their husbands were coming to celebrate her seventieth birthday.

So why did Crystal Balaclava go in fear for her life? Why did she use her still-considerable influence in high places to get Chief superintendent Henry Tibbett of Scotland Yard to join the party as her personal bodyguard? 'The wayward fancies of an elderly woman' - that was the Assistant Commissioner's view, and Henry was inclined to agree.

But his amused skepticism turns to nightmare when Crystal Balaclava literally drops dead at his feet, apparently poisoned - but by a non-existent poison. Was it indeed 'natural causes', as the police doctors and pathologists were forced to conclude? Or was it the perfect murder at last?

Henry, with his professional reputation at stake, determines to find out. But he is involved in a whirlwind trip around the Continent, an encounter with a beautiful woman doctor and a fight for his life before he finds the answer.

Once again Patricia Moyes lives up to her international reputation as a writer who 'puts the who back in whodunit' (Chicago Tribute), and whose name can now be mentioned in the same reverent breath as that of Agatha Christie, or Margery Allingham, or Ngaio Marsh' (Peter Phillips).

'Of all Miss Moyes's stories of Chief Superintendent Henry Tibbett and his wife Emmy, this, for really pretty classic detection, is far and away the best... a device as cunning as any since the great Sayers days of cunning devices.'

- The Times Literary Supplement

'Splendid houseparty murder with lots of suspects, mostly thoroughly unlikeable, plenty of ingenious twists and two really new ways to kill your rich relations. Great fun.'

- Francis Goff, Sunday Telegraph

'A thoroughly agreeable trad whodunit.'

Edmund Crispin, Sunday Times

'Who Saw Her Die? in fact shows Patricia Moyes at her most ingenious; and when original methods of murder are still being madly sought she walks off with a real lollapalooza.'

- Francis Iles, Guardian

'Miss Moyes is right up in the Agatha Christie entertainment class this time.'

- Northern Echo

'She is the only true post-war heir to the great tradition of British women detective story writers.'

- Anthony Lejeune, Tablet

'The most ingenious murder method used in crime-fiction for many years.'

- Birmingham Post

'When Miss Moyes writes a whodunit the question really is who. She is also consistently amusing and reliably entertaining.'

- Sheffield Morning Telegraph
