S10E10 Strange Bedfellows

Graham McVeigh, who runs a thoroughbred ranch, murders his brother and sets up a local mob bookmaker to take the fall. To cover his tracks, he then eliminates the bookie, passing it off as an act of self-defense. Meanwhile, mob leader Vincenzo Fortelli begins to tighten the screws on McVeigh. In order to unravel the case, Columbo finds himself forced to collaborate with the very gangster threatening McVeigh.
