It’s festival time in Saint Marie, but we all know what’s going to happen, don’t we?

That’s right – there’s a murder!

The victim’s husband interrupts the team’s festivities after a disturbing voicemail rouses
his suspicions.

But Jack (Ardal O’Hanlon) isn’t as sympathetic as he usually would be – the husband’s behaviour just doesn’t seem right to him. And then there’s the mystery of the yellow butterfly found near the body… which should be in hibernation at that time of year.

Where has it come from?

Meanwhile, Jack worries when he has to take Harry the lizard to the vet, and Dwayne
(Danny John-Jules) gets an exhausting taste of parenthood when Darlene’s niece comes to stay with him.
