I think it is because ACD created the characters and all their traits with which we are so familiar, and NG wrote a new story around them.

True. Her imagination and connecting new stories to the Classic Holmes/ Watson characters. Very well done. Personally ,I believe She has done a fantastic "Reinventing' cases and Redirecting the Great author ACD widely appreciated Sherlock Holmes / Dr.Watson adventures. I enjoy the British Mystery Authors very much and these new stories are exceptional. Also introducing Mystery Authors of the Victorian/ Edwardian Era's I've not been familiar with is rewarding . Thank you so much for introducing the public to these well done narrations . Bravo.✌️♥️🤩
