Gaius Petrius Ruso is a divorced and down-on his luck army doctor who has made the rash decision to seek his fortune in an inclement outpost of the Roman Empire, namely Britannia. His arrival in Deva (more commonly known as Chester, England) does little to improve his mood, and after a straight thirty six hour shift at the army hospital, he succumbs to a moment of weakness 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. A few years earlier, after he rescued Emperor Trajan from an earthquake in Antioch, Ruso seemed headed for glory: now he's living among heathens in a vermin-infested bachelor pad and must summon all his forensic knowledge to find a killer who may be after him next. Who are the true barbarians, the conquered or the conquerors? It's up to Ruso—certainly the most likeable sleuth to come out of the Roman Empire—to discover the truth. With a gift for comic timing and historic detail, Ruth Downie has conjured an ancient world as raucous and real as our own. Published in the UK as Medicus (Ruso) and the Disappearing Dancing Girls.

Army doctor Gaius Petreius Ruso strikes out for the uncivilized borders of Roman Britain in this highly anticipated sequel to Ruth Downie's New York Times bestselling debut. It is spring in the year 118, and Gaius Petreius Ruso has been stationed in the Roman-occupied province of Britannia for nearly a year. After his long and reluctant investigation of the murders of a handful of local prostitutes, Ruso needs to get away. With that in mind, he has volunteered for a posting with the army in Britannia's deepest recesses—a calmer place for a tired man. But the edge of the Roman Empire is a volatile place; the independent tribes of the North dwell near its borders. These hinterlands are the homeland of Ruso's slave, Tilla, who has scores of her own to settle there: Her tribespeople are fomenting a rebellion against Roman control, and her former lover is implicated in the grisly murder of a soldier. Ruso, filling in for the demented local doctor, is appalled to find that Tilla is still spending time with the prime suspect. Worse, he is honor-bound to try to prove the man innocent—and the army wrong—by finding another culprit. Soon both Ruso's and Tilla's lives are in jeopardy, as is the future of their burgeoning romance. Terra Incognita shines light on a remote corner of the ancient world, where Ruso's luck is running short—again.

The third novel in the acclaimed Gaius Petreius Ruso series by the New York Times bestselling Ruth Downie—this time set in ancient Gaul. Ruth Downie is published as R.S. Downie in the UK, and this book is available there under the title Ruso and the Root of All Evils. At long last, Gaius Petreius Ruso and his companion, Tilla, are headed home—to Gaul. Having received a note consisting only of the words "COME HOME!" Ruso has (reluctantly, of course) pulled up stakes and brought Tilla to meet his family. But the reception there is not what Ruso has hoped for: no one will admit to sending for him, and his brother Lucius is hoping he'll leave. With Tilla getting icy greetings from his relatives, Lucius' brother-in-law mysteriously drowned at sea, and the whole Ruso family teetering on the edge of bankruptcy, it's hard to imagine an unhappier reunion. That is, until Severus, the family's chief creditor, winds up dead, and the real trouble begins…

In her fourth novel, Ruth Downie brings to life the corruption and treachery of Roman-occupied Britain, as it closes in on her leading man, Gaius Petreius Ruso. 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.

Back at his post as a doctor in the Twentieth legion in Roman-occupied Britain, Ruso uncovers a new danger even closer to home than the neighboring barbarians. As mysterious injuries, and even deaths, begin to appear in the medical ledgers, it's clear that all is not well amongst the native recruits to Britannia's imperial army. Is the much-decorated Centurion Geminus preying on his weaker soldiers? And could this be related to the appearance of Emperor Hadrian? Bound by his sense of duty and ill-advised curiosity, Ruso begins to ask questions nobody wants to hear. Meanwhile his barbarian wife, Tilla, is finding out some of the answers-and 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.

The medicus Ruso and his wife Tilla are back in the borderlands of Britannia, this time helping to tend 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. Then Ruso's recently arrived clerk, Candidus, goes missing. A native boy thinks he sees a body being hidden inside the wall's half-finished stonework, and a worrying rumor begins to spread. When the soldiers ransack the nearby farms looking for Candidus, Tilla's tentative friendship with a local family turns to anger and disappointment. It's clear that the sacred rites to bless her marriage to Ruso will have to wait. Tensions only increase when Branan, the family's youngest son, also vanishes. He was last seen in the company of a lone and unidentified soldier who claimed he was taking the boy to see Tilla. As Ruso and Tilla try to solve the mystery of the two disappearances - while at the same time struggling to keep the peace between the Britons and the Romans - an intricate scheme involving slavery, changed identities, and fur trappers emerges, and it becomes imperative that Ruso find Branan before it's too late.

Ruso and Tilla and their new baby daughter have left Roman-occupied Britain for Rome, but their excitement at arriving in the city is soon dulled when they find 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 takes on 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 a friend 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' 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.

The eighth gripping novel in the bestselling Medicus series, in which Ruso and Tilla investigate the death of the wife of Ruso's friend in the sacred hot spring of Aquae Sulis. A scandal is threatening to engulf the popular spa town of Aquae Sulis (modern-day Bath). The wife of Ruso's best friend, Valens, has been found dead in the sacred hot spring, stabbed through the heart. Fearing the wrath of the goddess and the ruin of the tourist trade, the temple officials are keen to cover up what's happened. But the dead woman's father is demanding justice, and he's accusing Valens of murder. If Valens turns up to face trial, he will risk execution. If he doesn't, he'll lose his children. Ruso and Tilla do their best to help but it's difficult to get anyone—even Valens himself—to reveal what really happened. Could Ruso's friend really be guilty as charged?
