4. A Deadly Divorce

Bruce Firman is found dead in his garage by soon to be ex-wife, Margaret Benesch, and her daughter, Elizabeth Gatenby. Suspicion immediately falls on Benesch - as the sole heir in Firman's will, she is entitled to receive everything, but produces a rock-solid alibi. When investigators dust Gatenby's rental car for fingerprints, one match those of a 17-year-old teenager. He said he'd been hired to kill Firman by Gatenby's son, Byron, who confesses that his mother planned it all.
