The Box with Broken Seals

A fast-paced thriller with spies and U-boats and loads of secrets. Of course, they could have arrested the bad guy, and half the thrills would be out of the story, but of course they let him run about in a hope that he'll reveal his contacts, and of course that's the whole thing that drives the story. What's not a matter of course is the big twist ending that I sure didn't see coming! It's the ending that bumped it up to five stars for me.
