Query: Could be said to be "the final word" on the subject

The only reason this book got 4 starts instead of 5 is the slight anti-American tone at times (for example, the US inquiries are treated as a almost a joke) and something in this much detail could not help but be tedious at points (the discussion of "port" and "starboard" lights comes to mind),but it is extremely well-done, leaves no point untouched, examines minutely any evidence in Lord's favor, and comes to the point of the matter- he saw what he knew "might have been" distress rockets and did nothing- and really, that is the end of it.
