Here's what it's all about:
The Whitby Mermaid, prize exhibit of Cruickshanks’ Cabinet of Curiosities, has been stolen. But have no fear; consulting detective Gabriel Wraith is on the case. And he’s not the only one, for wherever there is a mystery to be solved, Ulysses Quicksilver is never very far away. What does the theft of what would appear to be a poorly-conceived fake have to do with the mysterious House of Monkeys? And what of the enigmatic criminal known only as the Magpie?
When Ulysses probes further into the case, he finds himself embarking upon an adventure that will take him to the industrially-polluted North of England and the fishing town where the curious creature was supposedly caught. But there are worse things awaiting him there than mermaids. The moors of Ghestdale are haunted by the savage Barghest beast, while in the abandoned mines beneath the Umbridge estate, impossible abominations lurk in the darkness, waiting. And yet Ulysses Quicksilver is about to discover that the worst horrors are those spawned by Man's own selfish nature.
Trapped within the very heart of darkness, with his body and sanity threatened, can he escape a fate worse than death with both still intact before one man's insane quest for immortality comes to fruition?
The novel includes the brand-new, specially-commissioned short story Christmas Past, and some unique Magna Britannia-style advertisements in the back.
