This is simply awful, a desperate attempt at the 'weekly murder in the sun' genre without the charm of Midsomer or the humour of Death in Paradise. Shayne Ward is sweet, if unlikely, as a retired policeman turned night club singer, but Catherine Tyldesley is a clunker as first mate. The absolute lack of actual police procedure and the glaring obviousness of the killer's identity only added to the heavy handed awkwardness. I would suggest you avoid this at all costs unless you're just trying to decide whether a cruise holiday is for you. The boat was very shiny, but floating petrie dishes aren't my thing.
