A blanket of fog grounds a flight in Brussels and Dr. Andrew Maclaren finds himself sharing a room with a fellow passenger who by morning disappears in suspicious circumstances, leaving behind an envelope hidden under the carpet. Whilst the contents are seemingly innocent, they lead the young Doctor into nightmarish adventures, culminating in the avoidance of cold-blooded killers in a deserted windmill and in the company of a beautiful redhead.

Eric Ambler was born into a family of entertainers and in his early years helped out as a puppeteer. However, he initially chose engineering as a full time career, although this quickly gave way to writing.In World War II he entered the army and looked likely to fight in the line, but was soon after commissioned and ended the war as assistant director of the army film unit and a Lieutenant-Colonel.This experience translated into civilian life and Ambler had a very successful career as a screen writer, receiving an Academy Award for his work on 'The Cruel Sea' by Nicolas Monsarrat in 1953. Many of his own works have been filmed, the most famous probably being 'Light of Day', filmed as 'Topkapi' under which title it is now published. He established a reputation as a thriller writer of extraordinary depth and originality and received many accolades during his lifetime, including two Edgar Awards from The Mystery Writers of America (best novel for 'Topkapi' and best biographical work for 'Here Lies Eric Ambler'), and two Gold Dagger Awards from the Crime Writer's Association ('Passage of Arms' and 'The Levanter'). Often credited as being the inventor of the modern political thriller, John Le Carre once described Ambler as 'the source on which we all draw'.A recurring theme in Ambler's works is the success of the well meaning yet somewhat bungling amateur who triumphs in the face of both adversity and hardened professionals. He wrote under his own name and also during the 1950's a series of novels as Eliot Reed, with Charles Rhodda. These are now published under the 'Ambler' umbrella.
