The Temple Dogs — Warren Murphy

Two prominent families steeped in the underworlds of New York and Tokyo clash in a tale of hard-won family honor, dark secrets, death, and betrayal. Inside Manhattan's tony Inn on the Park, a bride and groom beamed with the promise of new beginnings. Moments later they were dead. The murderer was the son a powerful Mafia family, Nick DeSanto. The bride was Susi Haverford, an ethereal half-Japanese girl descended from a legendary, and lethal, Yakuza clan. The only hope for justice is Susi's brother Miles, a young lawyer who must quickly learn to channel the long-buried savage inside to survive the battle of a lifetime. He turns his back on the West and returns to Tokyo to submerse himself in the ancient deadly arts of his ancestors. His focus on retaliation is clear – until he falls for a woman whose very existence threatens to undo all of his carefully laid plans.
