The fourth novel in the Second World War saga of the Bayley brothers. In the winter of 1942, it is the job of the youthful General Max Bayley, son of an English RAF World War I ace and a German mother, to protect transport planes dropping supplies to the stranded Wehrmacht in Russia. While Max's mission may seem doomed to failure, the Luftwaffe is facing worse problems on the Western Front, where they must face the formidable new RAF Mosquito. Reichsmarshal Goering soon realizes that the war cannot be won without the Mosquito, so orders military intelligence to obtain the specifications at any cost. This they endeavour to do by targeting the American wife of Squadron Leader John Bayley, Max's half-brother. But little do they reckon upon the might of the Bayley family... "The Whirlwind" tells the story of two young men united by blood and separated by ideology, and of the women they love and are desperate to rejoin.
