The third Richard Hannay adventure, following The 39 Steps and Greenmantle.
Brigadier-General Richard Hannay is recalled from duty on the Western Front to undertake a deadly, secret mission... tracking down and eliminating a German agent at large in Britain. From there he must travel deep into the Swiss Alps to prevent all of Europe from being overwhelmed by the might of the German army.
As Europe again heads towards war, Richard Hannay is persuaded to undertake one more mission to defend his country.
A new adventure for Richard Hannay coming later in 2016.
