Maverick

Cruise of the Cynthia B. (3x17)

Air date: Jan 10, 1960

Bret is one of the seven owners of a Riverboat who start down the Mississippi for Memphis to sell the broken-down craft, but soon, in a deadly game of 10 Little Indians, one owner after another is found mysteriously dead. It becomes apparent that if the boat does reach Memphis, it's almost certain it will have but one owner.
