Spy Sam Durrell heads into earthquake-ravaged Turkey to check on a U.S. radar station, on the Turkish-Russian border, that has gone silent; he ends up in the company of a disparate band of survivors, all of whom are double and triple crossing each other. Their escape from Turkey by military plane is short-circuited by Russian fighters, and Durrell fights for his life on the unforgiving Black Sea.
Another sturdy spy thriller from Edward S. Aarons, part of an admirable series that Aarons wrote in the 50s-60s for the less admirable Gold Medal pulp line. Aarons pens a tight little thriller and features more nuance in characters and situations than you might expect to see. A good entry in the series.
I bought this in a big chunk of Aarons novels on ebay some time ago and have been chewing through them steadily.
