Synopsis by Hal Erickson
Nancy Landon (Vera Miles) swoops down on Cabot Cove with the announcement that her son Steve (Richard Gilliland) had been fathered by the late husband of Jessica Fletcher (Angela Lansbury). With this in mind, Nancy insists that Jessica is obligated to help clear Steve fraud and murder charges related to the Landons' construction business. Though it pains her to do so, Jessica does what she can to prove Steve's innocence. Also in the cast is Martin Milner as Jessica's friend Clint Phelps, who may know more about the case than he's letting on.
