Narrative:
I prepared to depart on an IFR flight plan. I started the takeoff run and all gauges were green; indications and performance was normal. Towards the end of the takeoff run at approximately 98 KIAS; I rotated. As the airplane started to lift off; the right engine suddenly went to nearly zero torque and the airplane began to yaw and roll as would be expected with a sudden loss of power on a twin. Based on runway remaining; I elected to retard both power levers to flight idle and land on the runway. As I was in my landing roll and using brakes to decelerate; the right engine suddenly started to make a lot of torque and the airplane started to veer off centerline. I moved my hand off of the power levers (still at idle position) and moved the right condition lever full aft to mechanically shut down the engine and feather the prop so that I would be able to maintain directional control during the deceleration. The airplane stopped just beyond the asphalt surface in firm even level grass. I pushed the right firewall shutoff button as a precaution and proceeded to shut down the left engine normally. I helped the passengers egress.
