Nancy Grace will add a third hour of TV to her day. TVNewser has learned that beginning Monday, Grace will host a special live 9pm edition of her HLN show and devote it to missing persons. That show will air until Dr. Drew Pinsky‘s new HLN program debuts in the Spring.

Insiders tell us that during the 9pm hour Grace will profile different missing people every night, in the hopes of finding them. A few weeks ago, Grace’s viewers helped locate a missing Virginia girl, who turned up in San Francisco. Grace had been featuring the story of Brittany Smith on her show.

Grace recently re-signed with HLN after having discussions with Fox Business Network. She’ll continue to host her live show at 8pmET as well as her syndicated daytime show which is off to a strong start.
