Will a sticky murder spoil Humphrey and Martha’s romance?

Humphrey and Martha’s romance has been going far too well – yes, we’ve had some trademark awkwardness from our leading man, but otherwise it’s all been rather sweet and straightforward.

Time to liven things up with a murder, then! Well, this is a show about killings in the Caribbean…

The lovebirds nip over to a nearby island for a romantic getaway (because, you know, it would be impossible to feel romantic in boring old sun-drenched Saint Marie). There’s a shifty man staying in their hotel and before the duo have even dined, that man has met a sticky end.

Can Humphrey figure out what’s happened?

And with Martha’s time on Saint Marie short, can he move their relationship to the next level?
