    Good mystery intro; for younger readers
  

*by P***P on Reviewed in the United States on October 7, 2011*

Whenever I read Encyclopedia Brown I think of those bathroom books - you know, the ones with the five minute mysteries and logic puzzles. I think the Brown books are great at introducing the idea of deductive reasoning, but because of their episodic nature they really don't work too well as sustained works of fiction. That's why my hat is off to Ms. Barrett for this series.  Think how hard it is to come up with a decent mystery, and reasonable characters, in a short book intended for younger readers. Well, these Sherlock Holmes Files books probably come as close to pulling that off as can be expected. The sibling protagonists are appealing, and the usual sibling rivalry/teasing is kept to a minimum. Secondary characters are stock, but fairly effective. Everyone is very cheerful and helpful, and clues do just sort of poke out here and there, but I'm not sure there's anything you can do about that. The Sherlock Holmes connection adds a nice dash of color, and the references to actual Holmes stories will probably amuse adults who are helping or are reading to the youngsters.  So, if your reader likes hidden secret type mysteries, or if you want to try one out, this is a perfectly fine place to start.

Complete with a quaint English village, Henry the Eighth's mansion, boarding schools, and numerous art galleries, this book will please thrill-seeking readers.

    fun but unrealistic mystery
  

*by A***S on Reviewed in the United States on June 26, 2011*

I would have loved this book when I was a tween/teen but my kids thought the action was unrealistic and the characters too goody-goody. The story involves siblings Xena and Xander Holmes, who are visiting London with their parents; while there they discover that they are indeed descendants of Sherlock Holmes and they've inherited his book of unsolved cases. In this first outing they search for a missing painting and use deductive reasoning to discern its location. The mystery is interesting and the reasoning are plausible.
