Answering a call for help from an old friend, Biggles, Algy, Ginger and Smyth fly to Fort Beaver in Canada. There they intend to meet up with Wilks, or Captain Wilkinson of 187 Squadron as he used to be known.
Wilks has started a small airline business called 'Arctic Airways' but is having problems with a man named Jake 'Brindle' McBain and his cronies.
But when they arrive, Wilks is nowhere to be found, and Biggles gets an unfriendly reception...
A classic Biggles adventure, perfect for fans of Derek Robinson and Max Hennessy.
