This book was quite interesting becuase it actually starts from Irene Norton (Adler) who was known in one of Holmes adventures- "A scandal in Bohemia". Holes was eventaully was tricked by Irene, and eventually escapes. However, the newspaper said that both Godfrey Norton (Irene's husband) and Irene herself was dead in a train accident. Holmes eventually finds himself in a case in France (Monte Carlo) and went to Paris. He discovered that both Irene and Godfrey was alived, and had forgotten all grudges that were held upon her. Holmes knew that he couldn't solve the complete mystery if he only has "crumbs rather then the world cake itself." This book basically describes the whole adventure that Irene and Godfrey as well as Nell (works for Godfrey as a typist) escapes London and were in the middle of solving a mystery of the death of 3men with tatoos. I it quite interesting how Irene would the main character of the story for she really took no part in the adventures of Holmes and Watson. This veiw how other characters have their own open opinion about a certain area of how they feel about a certain character.(Hey, it's a free country)
