More an existential comedy of errors than a bona fide mystery, this week's "Monday Mystery Theatre" (TBS, 9 p.m.) is about a woman whose bad luck is almost hilariously morbid. In "Un no Nai Onna: Saigo no Tanjobi (The Luckless Woman: Last Birthday)," a woman named Satomi (Sachiko Sakurai) is celebrating her 30th birthday in a luxury condominium when she accidentally stabs her boyfriend and goes into a catatonic shock. Believing she has killed him she attempts to take her own life, but is interrupted when the boyfriend suddenly comes back to life -- at which point she really kills him.

Satomi embarks on a suicidal Odyssey in which each attempt to kill herself is spoiled. Intending to jump off the top of a tall building, she is caught by a security guard. About to throw herself in front of a train, she suddenly encounters a friend she hasn't seen in 15 years. The friend invites her to her junior high school reunion. Meanwhile, she keeps running into the same policeman.

One of the regular segments on the comedy show "Downtown DX" (Nihon TV, Wednesday, 10 p.m.), hosted by the manzai duo Downtown, is a segment where guests respond to postcards sent in by viewers describing sightings of the guests in everyday situations outside of their show-business lives. This week, the program will present a special made up completely of such sightings.
