About this listen

Another audiobook in the Tommy & Tuppence series.

It is World War II, and while the RAF struggles to keep the Luftwaffe at bay, Britain faces an even more sinister threat from ‘the enemy within’ – Nazis posing as ordinary citizens.

With pressure mounting, the Intelligence service appoints two unlikely spies, Tommy and Tuppence Beresford. Their mission: to seek out a man and a woman from among the colourful guests at Sans Souci, a seaside hotel. But this assignment is no stroll along the promenade. After all, N and M have just murdered Britain’s finest agent…

I love the Tommy and Tuppence series, more action in genre than Christies more notorious works but full of her trademark twists and turns. Hugh Fraser narrates this book excellently.

Another great story from Christie's dynamic duo!

As always this narration by Hugh Fraser is wonderful. His vocalisation of the different characters is clear and realistic.
loved everything about it.

Agatha Christie as always Brilliant

I love a good 'Aggy' - her unabridged descriptions and dialogues knocks the spots of any abridged dramatizations when read well, and Hugh Fraser does them justice.

I'm just beginning to explore the Tommy and Tuppence series and this is a delight, peppered with digs at young people's sexism and assumptions about older people.

BUT...

Does Audible HAVE to come in so soon and so loud after the reading ends. IT'S VERY INTRUSIVE AND BREAKS THE SPELL!!!

An unabridged performance
