Query: A very thorough investigation but slightly biased

This book is probably the most comprehensive collection of information on Anna Anderson, the woman who claimed to be Grand Duchess Anastasia. The book begins with what is known of Anderson's early life and continues until her death, spanning several decades, two continents and many court battles.However, I felt that the book leaned too heavily on the evidence that supported Anderson's claim. From the mystery's beginning until its conclusive end, there was always much evidence against the possibility on Anderson being Anastasia. Some is included in the book, but not dwelt upon as much as some of the other evidence.The updated section on the DNA testing is fascinating and very well written and should prove once and for all the claimant's identity, although some doubters still remain.Even though the mystery does conclude at the end of the book this is still a fascinating read, especially for anyone interested in Russian or royal history.
