The House of Silk

A new Sherlock Holmes novel, licensed by the Conan Doyle estate, this is set not long before the Reichenbach Falls incident, although it's told from the POV of a Watson living in a nursing home some time during World War I. There are obvious differences from Doyle's originals, not least of which is the length, which here is that of a modern novel, not the shorter works of the genuine canon.

It's quite a dark story, at times deliberately focussing on the seamier side of Victorian London, rather than the wealthier circles in which Holmes normally moved. Nor can one imagine Doyle writing about... well, what the story turns out to concern.

Still, it's quite a good pastiche of the style in other respects, and the story is twisty-turny enough, full of a lot of unsavoury characters doing their best to hide the secret of the House of Silk.
