Holmes investigates a major industry and finds there is more to smoke than meets the eye.
The Redacted Sherlock Holmes:
Orlando Pearson, Watson's successor as the assistant of Sherlock Holmes, was entrusted by the doctor with notes on cases too controversial to publish at the time.
Amongst other things these cases covered government failure to regulate the banks, excessively close links between a minister and industry, and an official cover-up of a sexual scandal at the very highest level in society.
It is inconceivable that such things could happen in the 21st century, but these stories, freshly unearthed, provide a fascinating insight into some of the issues facing society at the turn of the 20th.
