Shadow Island Mysteries The Last Christmas ( 2010 )

Tycoon grandpa La Foret revives his family's traditional Christmas gathering at the lodge Claire manages for him, five years after it ceased with the mysterious lake drowning of his daughter Anne. But it's a one-off, as he has terminal cancer. The traditional treasure-hunt will now designate his sole major heir. The relatives can set aside their mutual conflicts and team up, or waste their chances. Grandpa dies during the game time, but Sergio Boniti, his Venetian new personal assistant, is authorized to supervise the game before the professionals arrive. However Anne's death haunts the game, which already has her memory as theme.—KGF Vissers
