The First Man in Rome by Colleen McCullough

anyway, the two younger sons died, leaving the oldest son, Micipsa, to rule on alone. However, both his dead brothers had left children to complicate the future: two legitimate sons, and a bastard named Jugurtha. One of these young men would ascend the throne when Micipsa died—but which one? Then late in his life the hitherto childless Micipsa produced two sons of his own, Adherbal and Hiempsal. Thus did the court seethe with rivalries, for the ages of all these potential heirs were skewed exactly the wrong way around. Jugurtha the bastard was the oldest of them all, and the sons of the reigning King were mere babies.
    His grandfather Masinissa had despised Jugurtha, not so much because he was a bastard as because his mother was of the humblest stock in the kingdom: she was a nomad Berber girl. Micipsa inherited Masinissa's dislike of Jugurtha, and when he saw what a fine-looking and intelligent fellow Jugurtha had grown into, he found a way to eliminate this oldest potential contender for the throne. Scipio Aemilianus had demanded that Numidia send auxiliary troops to assist him at the siege of Numantia, so Micipsa dispatched his military levy under the command of Jugurtha, thinking Jugurtha would die in Spain.
    It didn't turn out that way. Jugurtha took to war as born warriors do; besides which, he made immediate friends among the Romans, two of whom he was to prize as his best and dearest friends. They were junior military tribunes attached to the staff of Scipio Aemilianus, and their names were Gaius Marius and Publius Rutilius Rufus. All three were the same age, twenty-three.
    At the close of the campaign, when Scipio Aemilianus summoned Jugurtha into his command tent to deliver a homily on the subject of dealing honorably with Rome rather than with any particular Romans, Jugurtha managed to keep a straight face. For if his exposure to Romans during the siege of Numantia had taught him anything about them, it was that almost all Romans who aspired to high public office were chronically short of money. In other words, they could be bought.
    On his return to Numidia, Jugurtha carried a letter from Scipio Aemilianus to King Micipsa. It extolled the bravery, good sense, and superior intelligence of Jugurtha so much that old Micipsa put away the dislike he had inherited from his father. And about the time that Gaius Sempronius Gracchus died in the Grove of Furrina beneath the Janiculan Hill, King Micipsa formally adopted Jugurtha and raised him to senior status among the heirs to the Numidian throne. However, he was careful to indicate that Jugurtha must never become king; his role was to assume the guardianship of Micipsa's own sons, now entering their early adolescence.
    Almost as soon as he had set this situation up, King Micipsa died, leaving two underage heirs to his throne and Jugurtha as regent. Within a year Micipsa's younger son, Hiempsal, was assassinated at Jugurtha's instigation; the older son, Adherbal, escaped Jugurtha's net and fled to Rome, where he presented himself to the Senate and demanded that Rome settle the affairs of Numidia and strip Jugurtha of all authority.

    "Why are we so afraid of them?" Jugurtha demanded, turning from his thoughts back to the present moment, the veil of soft rain drifting across the exercise fields and market gardens and obscuring the far bank of the Tiber completely.
    There were some twenty men on the loggia, but all save one were bodyguards. These were not gladiatorial hirelings, but Jugurtha's own men of Numidia—the same men, in fact, who had brought Jugurtha the head of young Prince Hiempsal seven years before, and followed up that gift five years later with the head of Prince Adherbal.
    The sole exception—and the man to whom Jugurtha had addressed his question—was a big, Semitic-looking man not far short of Jugurtha in size, sitting in a comfortable chair alongside his king. An outsider might have deemed them closely related by blood, which in actual fact they were;
