Who would want to spend christmas on Cape Cod in Granmother Davies's drafty old hours on the lonely beach, hidden in the winter fog? Marcie Williams shivers at the very idea. She's even more woried when she arrives on the Cape and meets Peter Doane. He's quiet, sensitive and good looking but oh so mysteriour.
Peter and his uncle are suspected of murdering a fisherman, Marcie believes Peter is innocent, but then who is it who prowls around the fisherman's abandoned hut? And who calls Marcie with the strange warning-and attacks her in the black of the night? Marcie is frightened, but she must stop whoever is out there--before it's too late.
