Please note, The Sinister Booksellers of Bath is a direct sequel to The Left Handed Booksellers of London. With that in mind it is entirely possible, if you’ve not read book one in this series, what follows might contain the odd spoiler or two. Consider yourself duly warned! There is often trouble of a mythical sort in Bath. The booksellers who police the Old World keep a careful watch there, particularly on the entity who inhabits the ancient hot spring. Yet this time it is not from Sulis Minerva that trouble starts. It comes from the discovery of a sorcerous map, leading left-handed bookseller Merlin into great danger. A desperate rescue is attempted by his sister the right-handed bookseller Vivien and their friend, art student Susan Arkshaw, who is still struggling to deal with her own recently discovered magical heritage. The map takes the trio to a place separated from this world, maintained by deadly sorcery performed by an Ancient Sovereign and guarded by monstrous living statues of Purbeck marble. But this is only the beginning, as the booksellers investigate centuries of disappearances and deaths and try to unravel the secrets of the murderous Lady of Stone, a serial killer…

Merlin is a young left-handed bookseller (one of the fighting ones), who with the right-handed booksellers (the intellectual ones), are an extended family of magical beings who police the mythic and legendary Old World when it intrudes on the modern world, in addition to running several bookshops. Susan’s search for her father begins with her mother’s possibly misremembered or misspelt surnames, a reading room ticket, and a silver cigarette case engraved with something that might be a coat of arms. Merlin has a quest of his own, to find the Old World entity who used ordinary criminals to kill his mother. As he and his sister, the right-handed bookseller Vivien, tread in the path of a botched or covered-up police investigation from years past, they find this quest strangely overlaps with Susan’s. Who or what was her father? Susan,…
