Based on one of Agatha Christie's books, "And Then There Were None", but an up to date version with gadgets like laptops and mobile phones. Despite that a fair bit of the dialogue and descriptions sound old fashioned. Several people have been invited by the enigmatic Lord Black to be guests on a Scottish island, but one by one, they are being murdered - by who and why? There was an interesting twist at the end, but it was a bit slow getting to it. On the whole I did like this book, but did prefer the original story. It would have been good to see a completely different version of this tale!
