In the first story, she makes reference to the space-time continuum. That was not even something that Victorian London was anywhere close to understanding, speculating on, let alone having it as a matter of study.
They also used carbon dating to see how old the pages in a book were. However, carbon dating did not premiere until the 1940s.
The second story Watson keeps referring to Holmes as Sherlock when describing his actions, he never referred to him by his first name. It was always Holmes.
Likewise, she has Mycroft referring to Watson as Watson, but in the Conan Doyle Canon he always respectfully referred to him as Dr. Watson.
Also, there is a brilliant chemist, who happens to be a woman. In Victorian, London, a woman was not even allowed to wait tables in restaurants, let alone be an award-winning chemist. This in no way is my agreeing with it, it is simply how things were in Victoria in London.
A metal prothetic hand with almost natural dexterity. Again, Victorian London only had hooks available as a prothesis.
Also, the study of eugenics was apparently being done in Victorian London also.
There were canon breaking inconsistencies as well, she had Holmes and Watson drinking tea, but they always had coffee with their breakfast if you read the Conan Doyle stories.
She painted Holmes as so emotionless that he would give a rare, an enigmatic smile. However, she used that expression several times throughout the stories.
She used a lot of modern idioms that would not be in Victorian language.
And in the third story in the book, she took an Agatha Christie approach, having all the suspects in one room and explain explaining in detail how it happened. But that is how Perot operated not Holmes. He never did the big reveal. And the reveal went on for 12 or more pages, to the point that I was eager to just finish with it.
Also, as an author and editor, there were several formatting errors that made it uncomfortable to read.
The book was not formatted for a gutter margin, so the words almost ran to the inside spine of the book instead of being set with margins that would push them away from the center.
There was no header format in the book.
She used a lot of inappropriate dashes, assuming she meant to use Em dashes, but she did not format it properly so they just came off as awkward, mini dashes when a comma would have worked.
Also, after picking up dialogue from the end of an action, she did not use the three dots that are required to illustrate that
As follows an example would be.
“I’m certain of this.” Holmes said as he picked the book off the table. “…as certain as I am that this book ties into the crime.”
