I completely and utterly adored this. I have been wanting to read it ever since whitecotton recced it, but I had to set sometime aside to read it and I managed that today on a horribly cold and wet Sunday afternoon.
I loved the crossover and how well you handled it, making the interaction between the two 'verses totally seemless. I loved the way that you portrayed all three of our heroes, including Draco. Not to mention, Holmes and Watson who were pitch perfect. I loved the time-travel aspect, I like time-travel fics as a genre, but this one as quite simply devine and I loved that you wrote it with the voice of John Watson as narrator, perfection itself, from the tone to the language use.
There are so many aspects of the story that I adored, including the original characters and the plot twists and I'd be here all night if I quoted them all. This is such a clever fic, yet it is also beautifully written and immensely readable
Every so often there is a story which goes right to the top of one's favourites list. This is such a fic in my opinion and I know I will come back to it again and again.
