DURING THE COURSE OF A WEEKEND, MARTIN SEARCHES FOR HIS MISSING AUNT AND JACK GETS DISTRESSING NEWS ABOUT HIS FATHER, ON A REBROADCAST OF "WITHOUT A TRACE," THURSDAY, AUG. 12

Martin Landau ("Mission Impossible") Guest Stars

"Shadows" -- Martin and Samantha search for his missing aunt during their weekend off, and Malone gets news that his father has Alzheimer�s, on a rebroadcast of WITHOUT A TRACE, Thursday, Aug. 12 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Randy Zisk directed the teleplay written by Jennifer Levin and Jan Nash. (Originally broadcast 4/15/04)

Martin Landau ("Mission Impossible") guest stars as Malone�s father.

After Martin�s Aunt Bonnie, a feeble cancer patient and nurse, vanishes for several hours, her concerned husband and adult daughters summon Martin to help find her. Enlisting Samantha�s assistance, Martin finds it difficult to be objective when some of the information they uncover suggests that his nurturing and seemingly proper aunt may have a secret lover, an unlawful business -- and/or a desire to commit suicide. Meanwhile, Malone, who learns that his combative father (Landau) is in the early stages of Alzheimer�s, decides to make an effort to make peace with him before it�s too late.
