## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    If you liked the first book in the series, you'll like this one too
  

*by J***R on Reviewed in the United States 🇺🇸 on February 5, 2018*

This book is part 2 in a series. If you liked the first book, you'll enjoy this one too. I'm giving it 4-stars because the ending isn't very clean. It seems more intent on setting up sales of book number three, than actually completing number two.

### ⭐⭐⭐⭐⭐ 







  
  
    The Downward Spiral...
  

*by M***H on Reviewed in the United States 🇺🇸 on January 27, 2018*

Loved this book.  Pearson did a great job at advancing the Moriarty/Sherlock Holmes story.  This time around, we begin to see James as a conspirator and a murderer.  Loved how it all played out.  Can't wait to read the next book.

### ⭐⭐⭐⭐⭐ 







  
  
    Quick reads because you can't put them down!

Loved the first book! The second did not disappoint, but left me wanting more. Can't wait for the next one.
