Narrative:

It was a routine reposition flight. The first officer and I departed at dusk and every indication in the preflight to cruise was routine and showed no sign of anything abnormal. We were cruising at our final altitude of 12;000 when about one hour into the flight we experience a #1 engine failure with no prior indication of such an event. We were met with a strong yaw to the left and after regaining control; we both confirmed it was an engine failure. We performed our immediate action items for an engine failure. After securing the #1 engine I directed the first officer to perform the engine failure checklist while I flew and conducted the radios. I informed center and they suggested ZZZ (25nm northeast of our location) which was the closest suitable airport to land at. I accepted the suggestion and then we made a 180 degree turn. After the engine failure checklist was completed; we preformed the descent checklist and then the approach and landing checklists. We made a normal landing single engine at ZZZ with no issues or problems. We canceled our IFR clearance with center upon clearing runway. We taxied single engine and made a normal shutdown. We went out to inspect the #1 engine and discovered an abnormal amount of oil at the rear of the engine nacelle; but other than the oil; nothing looked abnormal concerning the #1 engine.
