From the blurb:
‘In a Sea of Blackness…
A bank appraiser, expert at identifying counterfeit papers, is discovered quite dead in London’s financial district – but is it from natural causes or a cleverly disguised murder? Sherlock Holmes, ever the brilliant theorist, conducts his own brand of post-mortem as he leads Dr. Watson and a motley crew of confidence men on a chase through the most notorious neighbourhoods of London.
One primrose path leads to another – from the mystifying futures market to the most sensational costume ball in many a season. Lives, fortunes and careers are the stakes in this deadly game…and it’s up to the master sleuth and the good doctor to unmask the cunning culprits before another corpse is found.’
