Merula Merriweather has left Victorian London for Dartmoor with fellow zoologist Lord Raven Royston. The trip offers a unique treat, as they'll be staying with a friend with a collection of rare zoological specimens - including a kraken. But all is not right when they arrive. Their host's maid has vanished and the townspeople blame him, claiming that his specimens are alive and roam the moors at night. Merula and Raven are sceptical - then they find several specimen jars empty. Where is the missing girl? The pair are determined to find out, no matter what monstrous horrors they uncover.
