I read The Eagle Has Landed back in... was it middle school? Anyway, it left a strong impression on me and I was always kind of saddened by the ending; Colonel Steiner was too sympathetic a character to wind up like that.
So it made me happy to discover that there was a sequel: The Eagle Has Flown. And that it was a good read, too; fast-paced and filled with plenty of buckles getting swashed and derring being done. And I heartily approve of the ending.
(From a gun nut perspective, you just have to grin and bear it when a load of birdshot from a fowling piece sends someone flying over a balcony railing, "silencers" make guns whisper-quiet, or a S&W Victory Model gets stuffed in an ankle holster.)
