Tim Frazer, mystified by the disappearance of his ex-business partner, Harry Denston, is offered a job by a certain Mr. Ross. The Government department of which Ross is the head is very anxious to find Harry Denston and engages Frazer to search for him. Frazer's enquiries lead him to Talltree Cottage, the home of Mr. and Mrs. Edwards. Outside the house Frazer meets a girl named Anya... the name is startlingly familiar.
