Tony "The Butcher" Valtini is exactly what would be expected of a man with that sobriquet a big noise in the Mafia. He's also the victim of a fairly embarrassing crime, as some vigilante went Zorro on the softer segments of his anatomy, carving a L into his buttock with a sword. When Beckett and Castle track him to his lair he, it transpires, is she. Officer Ann Hastings, one of the 12th's own. Hastings confesses to the vigilante activity, but denies murder, and it doesn't take the duo long to figure out who wanted Lone Vengeance and Tyler Faris out of the picture - Tony Valtini.
