Follow That Witch, Pt. 1

S2, E30: Harriet, Abner's sister, is keeping house for him while Gladys is away. She finds that Gladys' stories of Samantha's unusual activities are true. Meanwhile Darrin is winding up a deal to handle advertising for the Robbins Baby-Food Company. Mr. Robbins, the president, agrees with his assistant, George Barkley, that the final decision should be deferred. Believing that anyone working on their account should be completely whole-some, Barkley, on his own, has hired Charlie Leach, a private detective, to shadow Darrin.
