In this novella set in 1924 London, ex-boxer Harry Stubbs is on the trail of a mysterious legacy. A polar explorer has died, leaving huge debts and hints of a priceless find. His informants seem to be talking in riddles, and Harry soon finds he isn't the only one on the trail - and what he's looking for is as lethal as it is valuable. The key to the enigma lies in an ancient Arabian book and it leads to something stranger and more horrifying than Harry could ever imagine.

Harry may not be an educated man, but he has an open mind, the bulldog persistence and fists like pile drivers - useful assets when you're boxing the darkest of shadows.

The story of mystery and horror draws on H.P. Lovecraft's Cthulhu Mythos and is inspired by Ernest Shackleton's incredible real-life adventures.
