Blue Lightning by Ann Cleeves

This mystery featuring Jimmy Perez of the Shetland police, takes place on Jimmy's home island of Fair Isle. Jimmy is visiting his parents with his fiance Fran. It is her introduction both to the island and to his parents. The weather is gearing up for a storm as they arrive, and the flight in is a bumpy one.
A lighthouse station at the north end of the island has automated and been renovated into a field centre for studying birds and plants. The head of station is Angela, with her husband Maurice doing most of the administrative work. Angela's assistant is Ben, and the cook and housekeeper for the centre is Jane. This is not a busy time for bird watchers, but there are four staying at the centre as this novel begins, two men and a married couple. Maurice's youngest daughter from his first marriage, Poppy, is also there.
Jimmy's parents have planned a party celebrating his engagement, and booked the field centre with Jane catering as the venue. The party goes well, but when a woman is found dead at the field centre the next morning, and the storm has hit in earnest, Jimmy finds himself investigating alone, something he isn't entirely comfortable with. It seems like the suspects are limited to those at the centre itself, but Angela's past behaviour and competitiveness have Jimmy looking into many motivations to make sense of the crime. When a second body is found, he knows that the killer is desperate and he must move quickly to prevent further deaths.
This is the fourth book in the series and seeing Jimmy back in his home island is interesting. I like both him and Fran as characters, and found the island fascinating.
