"Wasn't sure what to expect, but it was a lot of fun. There are so many details to find among all the documents. I enjoyed Watson's narration as well, felt like authentic Doyle."

Having penned a play about a secret society known as Cauda Draconis, a playwright begins to receive cryptic threats.
Desperate, he turns to Dr. Watson, who reluctantly takes on the case without his companion and friend, Sherlock Holmes. But despite Watson standing guard outside, the playwright is killed in his own home.
Who could have bypassed Watson and perpetrated the crime? Anyone hoping to answer that question will need a keen eye for detail and the capacity to think outside the box.
