Ricardo Montalban plays a man named Václav Maryska, and Václav is a Czech name. Having the Mexican-American playing a Czech is ridiculous...though once, Montalban played a Japanese man on "Hawaii Five-O"!! You need to look past this goofy casting decision when you watch "Murder in F Sharp".
Early in the show, Václav (Montalban) stops playing the piano in the middle of a concert...declaring he cannot play an instrument that is out of tune. Soon after, there's an apparent accident and the man's hands are badly burned...and it turns out the pianist had an insurance policy for $10,000,000 if his hands were injured. Not surprisingly, Dennis Stanton (Keith Mitchell) investigates the case to see if it really was an accident. Surprisingly, very shortly after, Maryska's wife is murdered...and there's policy on her as well. Can Stanton figure all this out and save his company a fortune?
This episode has two things against it. First, like many weak episodes, Angela Lansbury is only there to introduce the show. Second, while I love the Stanton character, the plot is weak...and the solution to all this VERY obvious. Still, despite these problems, it is enjoyable...as would any session with Stanton.
