270 AD Rome has ruled Syria for over three centuries. But now the weakened empire faces a desperate threat: Queen Zenobia of Palmyra has turned her Roman-trained army against her former masters and the once invincible legions have been crushed. Arabia, Palestine and Egypt have fallen and now Antioch, Syria's capital, stands exposed. Cassius Corbulo is a young intelligence agent fresh from officer training. He has been assigned the menial task of rounding up wounded legionaries but then urgent new orders arrive. He is the only ranking Roman officer left in the line of the Palmyran advance. He must take command of the fort of Alauran, the last stronghold still in Roman hands, and hold it against the enemy until reinforcements arrive. What Cassius finds at Alauran would daunt the most seasoned veteran, let alone a nineteen year old with no experience of war. A mere scattering of divided and demoralised legionaries remain, backed up by some fractious Syrian auxiliaries and a drunken Praetorian Guardsman. With the Palmyrans just days away, Cassius must somehow find the discipline, resourcefulness and courage to organise the garrison, save Alauran and secure Rome's eastern frontier...
The Roman Emperor Aurelian has defeated Queen Zenobia and crushed the Palmyran revolt, but now dark forces threaten a fragile peace, in the sequel to The Siege Faridun's Banner, hallowed battle standard of the Persian Empire, has fallen into Roman hands and is to be returned to the Persians as part of a crucial peace treaty. But on the eve of the signing the banner is stolen. Recalled to Syria, imperial agent Cassius Corbulo is charged with recovering the flag. Accompanied by his faithful servant Simo and ex-gladiator bodyguard Indavara, Cassius must journey across the dangerous Syrian desert to the equally perilous streets of Antioch. He and his companions face ruthless brigands, mysterious cults, merciless assassins, and intrigue at every turn. The hunt is on.
When the deputy commander of Rome's Imperial Security Service is assassinated on the island of Rhodes, Cassius Corbulo swiftly finds himself embroiled in the investigation. Assisted once more by ex-gladiator bodyguard Indavara and servant Simo, his search for the truth is complicated by the involvement of the dead man's headstrong daughter, Annia. Braving hostile seas, Cassius and his allies follow the assassin's trail south aboard a ship captained by a roguish Carthaginian smuggler and manned by his disparate, dangerous crew. Their journey leads them to the farthest reaches of the empire; to a ruined city where the rules of Roman civilization have long been abandoned, and a deadly battle of wits with a brutal, relentless foe.
A source of a fabulous power lies on the heart of an enemy's kingdom, in the fourth adventure featuring Cassius Corbulo, a detective in the highly secretive Imperial Security Service AD 273. Obsessed by the solar religions of the east, the emperor Aurelian sets out to obtain every sacred object within his realm. But one—a conical rock said to channel the very voices of the gods—lies beyond his reach. Arabian king Amir Adi has captured the stone and intends to use its fabled power to raise an army against Rome. For imperial agent Cassius Corbulo and his bodyguard Indavara, recovering the stone will constitute their toughest mission yet.
Still recovering from his previous assignment in Arabia, imperial agent Cassius Corbulo has been spending most of his time and money on women and wine. Unfortunately for him, word of his achievements has reached the emperor Aurelian's deputy and he is sent north, tasked with smashing a counterfeiting gang. Cassius tracks the criminals to the city of Berytus, where his investigations are hampered by civil unrest and uncooperative officials, not to mention the personal problems of his servant Simo and bodyguard Indavara. Despite this - and intense pressure from his superiors - the young officer eventually closes in on the gang. But his enemies will do anything to protect their profits, and Cassius and Indavara soon find themselves fighting not only for the emperor, but for their very survival.
Unable to make any progress in locating the missing Indavara, a desperate Cassius has been given an unrewarding assignment in Antioch. But when an old ally's daughter is kidnapped, he feels duty-bound to repay a long standing debt. Disillusioned with the tawdry demands of the Imperial Security Service, he disobeys his superiors and leaves Syria, determined to do some good. Accompanied by nomadic chieftain Kabir and a trio of warriors, Cassius soon finds himself in Greece hunting a vicious band of slave-traders trafficking women across the Empire. But these are no common criminals, and as Cassius sets out to bring them down, he finds himself up against ruthless, cunning men with powerful friends and a lot to lose. For the Agent of Rome, desperate times call for desperate measures.
