This was nice little spy novel - suggested by Charles Stross of all people.
It revolves around one Dr. David Audley, a Middle East expert who gets a little too accurate and too strident for the comfort of politicians in the Ministry of Defense and is turfed out to field which work. Something he doesn't like doing.
The field work involves a recovered Dakota bomber - lost after WW II smuggling something out of Berlin. Something the Soviets are still interested in even 25 years later. Along the way Audley discovers he likes field work a bit too much for his taste and comfort, uses his network of academics and Middle East experts (some spies) to good effect. He's also lucky and knows it - to his discomfort.
