These are two absolute classics of this genre, by the Queen of Crime herself. Murder on the Orient Express features a group of passengers trapped on a train in a blizzard, while And Then There Were None 's characters are stranded on a mysterious isolated island.
A group of guests have gathered together at a grand old estate to play "The Murder Game", but soon of them is murdered for real.
My absolute favorite book for the last twenty years! A group of people have all been enticed to move into a new apartment building when a murder occurs. They are snowed in, and have to take part in a mysterious game in an attempt to solve the murder and win big.
