The name is a pun on an Agatha Christie story. The inspiration id William Shakespeare's Romeo & Juliet.
The Montgomery's and Caplan's have been rival bakers across the street for generations. Now it seems that people are being poisoned from products made by both bakeries. Both Terry and Gemma hire themselves out to each of the bakers to investigate. It's a win-win for them.
Gemma's sister, Monica is involved in a production of Romeo & Juliet sponsored by the bakers. Unfortunately some of the cast got poisoned and may be in further danger.
Maybe the offsprings of the Montgomery's and Caplan's are involved in a twisted plan. Could they be heading for a fall?
A mixture of hammy acting, bad plotting but this is an improvement from the first episode. Some of the gags are even good.
