The object I drew out was dusty and mildewed, and blotched with dark rust-coloured stains. It smelt of time and decay, sour, like old books and parchments. The light from the chapel's stained-glass window blushed red upon it, and upon my hands, as if the thing itself radiated a bloody glow.

Ramshackle and crumbling, trapped in the past and resisting the future, St Saviour's Infirmary awaits demolition. Within its stinking wards and cramped corridors the doctors bicker and fight. Ambition, jealousy and hatred seethe beneath the veneer of professional courtesy. Always an outsider, and with a secret of her own to hide, apothecary Jem Flockhart observes everything, but says nothing.

And then six tiny coffins are uncovered, inside each a handful of dried flowers and a bundle of mouldering rags. When Jem comes across these strange relics hidden inside the infirmary's old chapel, her quest to understand their meaning prises open a long-forgotten past - with fatal consequences.

'Beloved Poison is a marvellous, vivid book . . . I was surprised to see twenty-first century London rather than grimy, smelly St Saviour's around me when I - eventually - looked up from its pages' - Janet Ellis, author of The Butcher's Hook
