Jeff is approached by happily married Margot Wendice, as she has been blackmailed by an unknown person who was able to steal what could be seen as a compromising letter from her purse which could implicate her in an extramarital affair. Rather than come clean to her husband Tony Wendice about the innocence of the undated letter which was written several years ago by her former fiancé before Tony even came into her life, she decided to pay off the blackmailer. However, the letter was never returned to her after payment. The reason she approached Jeff specifically is not so much in a professional capacity, but rather because he is the said ex-fiancé, who broke up with her when he was called back into military service for the Korean War, he not wanting her either to wait for him or in the possibility that he would be disabled or killed. Jeff encourages Margot still to tell Tony the truth to get ahead of the blackmailer, who would no longer have anything with which to blackmail. What they are unaware of is that Tony himself is the blackmailer, who was testing his wife with the scheme to see if she would come clean to an affair. Not having done so, Tony moves to Plan B: have her killed, her death which would enable him to inherit the sizable estate she brought into the marriage, something he would not get in a divorce. That plan would include an airtight alibi for himself when she would be killed. This situation ends up with Jeff being implicated in a murder, which Stuart, with Kookie by his side, has to investigate if Jeff has any chance of clearing his name.
