In 1920s Scotland a foreign dignitary on a secret visit has been abducted by men who plan to murder him.

Veteran adventurer Richard Hannay must recruit three of his oldest friends to prevent a catastrophe that could plunge Europe into another war. It is a mission none of them ever expected to undertake, for the man they must rescue was once their sworn enemy – the Kaiser.

As he and his allies pursue a desperate chase through the Highlands, Hannay discovers that he has stumbled upon an international conspiracy, one that shockingly involves a member of the British royal family.

In Castle Macnab Robert J. Harris, bestselling author of The Thirty-One Kings, has created a new adventure for Richard Hannay and a sequel to John Buchan’s classic novel John Macnab.

"

'an entertaining new adventure ... [t]here’s genuine empathy for those affected by the Great War, and it shows how emotional damage distorts ethical values for men and women of all backgrounds. A yarn with a heart'

"

'Harris makes [Buchan's] creatures and places accessible by virtue of their honour, their wit their courage and by immersing them in a rattling good plot. "Richard Hannay Lives", if he ever died'

"

'Suitably swashbuckling, with plenty of nods to Buchan’s other novels and works. Good fun and an admiring tribute'
