Ruth Downie books in order

Ruth Downie is a British author of historical mystery and historical fiction novels.

Born in North Devon, England, Downie never had aspirations of becoming a writer while growing up, a fact that might surprise some of her readers.

Armed with an English degree, her grand scheme had always been to get married and lead a life filled with everlasting happiness.

However, while on an educational family trip to Hadrian's Wall, Downie’s creativity was sparked when she read that Roman soldiers could engage in relationships with local women but were prohibited from marrying them.

This marked the beginning of a journey that ultimately led to the birth of the Medicus Investigation Series.

Whenever she isn’t immersed in research or writing the Ruso novels, Downie indulges in the occasional, delightful week of archaeological excavation in an attempt to unearth the remnants of Roman Britain.

Medicus Investigation


Divorced and down on his luck, Gaius Petreius Ruso has made the rash decision to seek his fortune in an inclement outpost of the Roman Empire, namely Britannia. In a moment of weakness, after a straight thirtysix-hour shift at the army hospital, he succumbs to compassion and rescues an injured slave girl, Tilla, from the hands of her abusive owner.

Now he has a new problem: a slave who won't talk and can't cook, and drags trouble in her wake. Before he knows it, Ruso is caught in the middle of an investigation into the deaths of prostitutes working out of the local bar. Now Ruso must summon all his forensic knowledge to find a killer who may be after him next.

With a gift for comic timing and historical detail, Ruth Downie has conjured an ancient world as raucous and real as our own.

Terra Incognita

It is spring in the year of 118, and Hadrian has been Emperor of Rome for less than a year. After getting involved with the murders of local prostitutes in the town of Deva, Doctor Gaius Petreius Ruso needs to get out of town, so has volunteered for a posting with the Army on the volatile border where the Roman-controlled half of Britannia meets the independent tribes of the North. Not only is he going to the hinterlands of the hinterlands, but it his slave Tilla's homeland and she has some scores to settle there.

Soon they find that Tilla's tribespeople are being encouraged to rebel against Roman control by a mysterious leader known as the Stag Man, and her former lover is implicated in the grisly murder of a soldier. Ruso, unwillingly involved in the investigation of the murder, is appalled to find that Tilla is still spending time with the lover. Worse, he is honor bound to try to prove the man innocent - and the Army wrong - by finding another suspect. Soon both Ruso's and Tilla's lives are in jeopardy, as is the future of their burgeoning romantic relationship.

At long last, Gaius Petreius Ruso and his companion, Tilla, are headed home to Gaul. But with Tilla getting icy greetings from Ruso's relatives, a family member having mysteriously drowned at sea, and the whole Ruso household teetering on the edge of bankruptcy, it's hard to imagine an unhappier reunion.

Caveat Emptor

Ruso and Tilla, now newlyweds, have moved back to Britannia, where Ruso's old friend and colleague Valens has promised to help him find work. But it isn't the kind of work he'd had in mind-Ruso is tasked with hunting down a missing tax man named Julius Asper.

Of course, there's also something else missing: money. And the council of the town of Verulamium is bickering over what's become of it. Compelled to delve deeper by a threat from his old sparring partner, Metellus, Ruso discovers that the good townsfolk may not be as loyal to Rome as they like to appear.

While Tilla tries to comfort Asper's wife, an anonymous well-wisher is busy warning the couple to get away from the case before they get hurt. Despite our hero's best efforts to get himself fired as investigator, he and his bride find themselves trapped at the heart of an increasingly treacherous conspiracy involving theft, forgery, buried treasure, and the legacy of Boudica, the Rebel Queen.

NB: This book is also known as Ruso and the River of Darkness.

Semper Fidelis

When Ruso rejoins his unit in the remote outpost of the Roman Empire known as Britannia, he finds that all is not well with the Twentieth Legion. As they keep a suspicious eye on the barbarians to the north, the legionaries appear to have found trouble even closer to home-among the native recruits to Britannia's imperial army.

A young soldier has jumped off a roof, killing himself. Why? Mysterious injuries, and even deaths, begin to pile up in Ruso's medical ledgers, and it soon becomes clear that this suicide is not an isolated incident. Can the men really be under a curse? And what has this to do with the much-decorated Centurion Geminus?

Bound by his sense of duty and compelled by his ill-advised curiosity, Ruso begins to ask questions nobody wants to hear. Meanwhile his barbarian wife, Tilla, starts to find out some of the answers-and is marked as a security risk by the very officers Ruso is interrogating.

With Hadrian's visit looming large, the fates of the legion, Tilla, and Ruso himself hang in the balance.

Tabula Rasa

The medicus Ruso and his wife, Tilla, are back in the borderlands of Britannia, where he is tending the builders of Hadrian's Great Wall. Having been forced to move off their land, the Britons are distinctly on edge and are still smarting from the failure of a recent rebellion that claimed many lives.

The tension grows when Ruso's recently arrived clerk goes missing and things go from bad to worse when the young son of a local family also vanishes. While struggling to keep the peace between the Britons and the Romans, Ruso and Tilla uncover an intricate deception involving slavery and fur trappers, and it becomes imperative that they solve the mystery of the two disappearances before it's too late.

Vita Brevis

Ruso and Tilla and their new baby daughter have left Roman-occupied Britain--and the military--for Rome at the urging of Ruso's patron, Accius. Their excitement upon arriving is soon dulled by the discovery that the grand facades of polished marble mask an underworld of corrupt landlords and vermin-infested tenements. There are also far too many doctors--some skilled, but others positively dangerous.

Ruso thinks he has been offered a reputable medical practice only to find that his predecessor, Doctor Kleitos, has fled, leaving a dead man in a barrel on the doorstep and the warning, "Be careful who you trust." Distracted by the body and his efforts to help Accius win the hand of a rich young heiress, Ruso makes a grave mistake, causing him to question both his competence and his integrity.

With Ruso's reputation under threat, he and Tilla must protect their small family from Doctor Kleitos's debt collectors and find allies in their new home while they track down the vanished doctor and find out the truth about the unfortunate man in the barrel.
