Ruth is the author of nine mysteries* featuring Roman Army medic Gaius Petreius Ruso and his British partner Tilla. The latest is a novella, PRIMA FACIE. She lives in Devon, England. A combination of nosiness and a childish fascination with mud means she is never happier than when wielding an archaeological trowel. She is sometimes called R.S. Downie, but she isn't the person with the same name who writes medical textbooks, and recommends that readers should never, ever take health advice from a two thousand year old man who prescribes mouse droppings. *The first four books have all had two titles. Ruth is still wondering how this ever seemed like a good idea. Since she is unable to wind back time, British readers may find it useful to know that: Medicus was Ruso and the Disappearing Dancing Girls, Terra Incognita was Ruso and the Demented Doctor, Persona Non Grata was Ruso and the Root of All Evils, Caveat Emptor was Ruso and the River of Darkness - but SEMPER FIDELIS, TABULA RASA, VITA BREVIS, MEMENTO MORI and PRIMA FACIE only have one title each - hooray!
