Having accumulated $67,000 from a gold strike, prospector Chris Keller (Christopher Connelly) finds himself the target of virtually every confidence trickster in the country. To save himself and his cash, Chris hides out at the Ponderosa, only to be lured into the open by lovely Charity McGill (Elaine Giftos). By an amazing coincidence, sweet Charity needs $65,000 to pay for her dear father's medical expenses. The Cartwrights are certain that Charity is yet another con artist-but is she? Ralph Waite of The Waltons fame appears in the supporting role of Hoby. Written by Preston Wood, "The Lady and the Mark" first aired February 1, 1970, then was chosen by NBC for an encore presentation in June of 1972. ~ Hal Erickson, Rovi
