Dressed in Cape-coat and deerstalker, the Doctor and Sarah land in Victorian Britain and get embroiled in a mystery. He's accompanied by a young doctor, Arthur Conan Doyle, who has dreams of being an author.
It's fascinating watching the Doctor act in a Holmesian fashion and (so we deduce) how the mannerisms are retained by Doyle for future reference. Equally for resourceful Sarah, the friend that would (again we deduce) help to shape Dr Watson, along with Doyle's tagging along with the Doctor. We even meet ragamuffins who are able to spy-out, led by Billy. Again, author John Peel takes these from the Holmes universe and skilfully transplants them here; whilst within the book, Conan Doyle will take these elements from his experience and eventually transplant them to his famous detective.
From a nerdy point of view(1), this book asks, if you wish to go down that road, Who created Sherlock Holmes? Was it Conan Doyle with the Doctor freely copying, or was it the Doctor who Conan Doyle freely copied from? Ultimately, Conan Doyle did come up with the Speckled Band, Red Headed League, the Solitary Cyclist et al independently of this adventure.
And the literary icons don't stop there as Sarah spends a lot of her time with 15 year old Rudyard Kipling, investigating what is at first a separate mystery on missing children.
The gothic atmosphere that runs throughout the book is very good, and Peel's writing engaging. I was curious about the mysteries and I read the book at pace, thoroughly recommending it. Despite the appearances of Kipling and Doyle, this is a science fiction book, with shades of Dr Moreau. It also has a very subtle, but noticeable, link to the TV story Horror of Fang Rock.
The various strands at the beginning do come together at the conclusion when the plot's revealed, and a good plot it is too. Very satisfying.
From a nerdy point of view(2), this book clearly implies that Conan Doyle will go on to write Holmes (who'd be fictional), yet this same publishing company would publish a seventh Doctor book where the Doctor meets Holmes and Watson. How do they square that, does anyone know?
From a nerdy point of view(3),I believe this (probably) influences Conan Doyle Professor Challenger series, but I've not read them, so I guess I'm missing out on some very clever clues and hints.
I do have problems with scoring this book though. As I hope you can tell from the above, I loved it. However, it never felt like a Dr Who book. I never had Tom Baker or Elizabeth Sladen in my head when their characters spoke or acted, especially where Sarah's about to be mutilated her reaction felt more like Ace or Leela.
On reflection, I guess the overriding factor should be, as I enjoyed it, I'd rate it as 8/10
Scoring: 0 absolutely rubbish; 1-3 poor; 4-6 average; 7-9 good; 10 excellent.
