Bonnie Valin confesses to Mark she arranged for him to get her off for the greedy laughing gas murder on her husband plastic surgeon Elliot, trusting the double jeopardy rule renders her immune to prosecution. Steve is nearly demoted, and forced to prosecute the innocent son and true heir, Roger Valin. Meanwhile Jack is determined to get Amanda's embezzled trust fund back by posing as the seller and later buyer of the missing can of Campbell soup painting, for which he knows a perfect forger.

No Laughing Matter-Episode **1/2
19 February 2013 | by (United States) – See all my reviews

Am reviewing the entire episode here-parts 1 and 2.

When a surgeon, Purnell Roberts, in a rather brief appearance, is scheduled to be honored and then mysteriously murdered, his estranged son, who he had argued with just before the murder, is the natural suspect.

Of course, Roberts, who had been having an affair, is on his 2nd wife, a cunning Dyan Cannon.

When the pendulum turns and Cannon is fingered for his murder, Dr. Sloan is able to provide evidence that she is not guilty. She is exonerated and his son is promptly arrested.

When Sloan finds out that he has been mistaken and that Cannon indeed was the killer, he sets out to get her. Remember she can't be subjected to the double jeopardy provision of the law.

The entire episode suffers because of the sidebar story. When Victoria's financial adviser begins stealing from her and she loses just about everything, she sets about trying to turn the tables on him with co-doctor Scott Baio. How they dress up-she looking just like a hooker is funny, but as their episode goes on, it becomes more and more unsettling. You can't wait for this part to be over.
