Sebastian St. Cyr, Viscount Devlin, is drawn into the investigation by his valet, Jules Calhoun, an old friend of the dead man. With Calhoun's help, Sebastian begins to piece together the shattered life of the late Earl's ill-fated youngest son. Why did Nicholas risk his life and freedom by returning to England? And why did he bring the now-missing young boy with him? Several nervous Londoners had reason to fear that Nicholas Hayes had returned to kill them. One of them might have decided to kill him first.
