Buried Angels

I enjoyed Buried Angels by Camilla Lackberg which is set on a small Swedish island.  A young married couple, Tobias and Ebba, go to live and renovate Ebba's childhood home.  The house has a mysterious history as when Ebba was a toddler her whole family disappeared, apparently when they were eating lunch.  At the time the house was an exclusive boarding school run by Ebba's father.  At the time the family disappeared there were five boys staying there but they were out fishing when the family disappeared.  On alternate chapters we read about an horrific crime that happened early in the 20th century.  The reader follows this story until it catches up with the present.  There are mysteries to be solved and there are many characters to follow - too many.  31/2/5
