Despite being a big Shetland fan, I think this is actually the first book by this author I can remember reading.  An interesting start to a likely new series of books, Matthew is an interesting lead character with I'm sure an interesting background that will likely play into later books in the series.

When a body is found on the beach Matthew and his team must work to discover what happened.  They discover a link to the day care centre where Matthew's husband works, and when two women from there are kidnapped, the case just gets more confusing - what could be the link?

Hints of homophobia in small town Devon, a DS who also has history (single Mum with a potentially violent ex-partner), a DC who's a bit too big for his boots and is indiscreet with the boss... so many options for which way future stories can go.

Well-written, interesting characters and I will likely look out for more books in this series
