Query: Not up to his best

I found this to be a slow moving story that had a good premise with a weak outcome. A corporal being escorted to Cairo to be tried for the murder of his commanding officer changes place with the military policeman guarding him when the latter dies of a heart attack. Upon arrival, the policeman was to have led a search for a spy in Egypt supplying Rommel with military secrets. Great premise, but the book was uninteresting and contrived from that point on. I finished it, but wouldn't have minded if I hadn't. I see it's out of print and relatively unobtainable (I got mine on a bargain book table) which is where it belongs.
