As I couldn't find any information on Chandana Mendis's Sherlock Holmes books, I won't be able to provide a review of the books themselves. If you're interested in reading Sherlock Holmes books, I recommend exploring the original works by Sir Arthur Conan Doyle or other well-known authors who have written pastiches or sequels.

If you have any more information about Chandana Mendis or the specific books you're looking for, I'd be happy to try and help you further!

However, I did find that there are several authors who have written Sherlock Holmes books, including Sir Arthur Conan Doyle, who is the original creator of the character. There are also many other authors who have written pastiches, sequels, or adaptations of the Sherlock Holmes stories.
