Query: Improbable and trite, are his books getting worse?

"Captain" continues a slide in quality in Shelley's writing since the "Buchanan Campaign". The book starts with an inexplicable romance which leads you to question whether Nolan (the hero) should be trusted with a rifle, let alone commanding troops. An interlude involving field-testing a new logistics system leads nowhere; I had assumed it would play some part later in the book. Lastly the political situation into which the DMC is thrust seems wholly unreal. Or, if the situation doesn't, the protaganists' actions and the eventual plot developments leading from them strain disbelief. Simply awful.
