Moffat, a murderous and magniloquent criminal, is thriving in the underbelly of 19th-century London. When he unexpectedly inherits Gibbous House, an expansive estate in Northumbria, he heads north on a journey that raises questions about his own identity and quickly leads to issues of morality, addiction and murder. Gibbous House, Moffat discovers, already plays home to a motley cast of characters: the beautiful and seductive Ellen Pardoner, the conniving attaché Maccabi and the arrogant scientist Enoch—manager of the mansion's esoteric 'collection'. Moffat's greed-fuelled pursuit of his inheritance takes him deep into a crazed, conspiratorial plot and a series of tense psychological showdowns. Gibbous House is a dark Victorian thriller told with fresh wit and brimming with historical detail. Filled with atmosphere and drama, it brings modern irony to the rich texture of the classic gothic novel.
