A locked room mystery (but the room is an island this time).

A good old fashioned 'locked room' mystery object this time the murder Took Place on an island from qui There Was no way off. Interesting cast of characters and the added bonus That It takes up in Sweden, so squares, streets, etc., if you arent familiar-have never been to this country.
After about half way I found this a real page-turner, unput-downable.
