The Plumber

Orphaned and alone on the streets of East London, Ian Barnabels' future seemed written in hardship. Forced into backbreaking construction work as a teenager, he found salvation in the one institution that offered structure: the army. There, he discovered a terrifying gift. A natural marksman, he could thread a needle with a bullet from two kilometers away. But his talent made him a target. When he rejected the advances of a vengeful sergeant, she destroyed his career with a false accusation.
Though the court vindicated him, her retaliation was far from over, she sent killers to finish the job. In a final act of self-preservation, the hunter became the hunted, and Ian executed his former tormentor. Now a ghost, he reinvented himself as a private security contractor in Iraq. It was there he met Captain Raglan, a British intelligence officer who saw Ian's lethal skill not as a curse, but as a business opportunity.
Together, they forged a deadly partnership, becoming the most sought-after assassination team in the shadows. But every killer makes enemies. After crossing MI6, they were forced to flee to the winding streets of Turin, where Ian's past finally caught up with him in the form of an old Irish detective. The confrontation was as brief as it was final, closing the bloody chapter of his life for good.
