Shetland Series #4. I had got #5 for Christmas, so had to get all the others as well :-). At first I liked Jimmy Perez and the island, but then I got a little bored with the series (and Fran). As Fran was killed in #3, I suspected to like the next ones better, and I was right.
This one has much more Shetland in it than the other ones (or maybe this is just my impression), which I thought great. Although I get motion sickness nearly everywhere theoretically I am fond of sailing, and there is quite some of it in this book.
Willow somehow seems a twin to Annie from die DCI Banks series by Peter Robinson, but as I like Annie, this is totally ok with me.

I am a little irritated by the photo of the actor BBC casted - it is mentioned quite often how dark Jimmy Perez is ... and the whole Spanish Armada story. Well.
