Widower Kevan de Vries returns to 'Sausage Hall', his house in Sutterton, after seven years' exile in St Lucia. He must remain incognito because police want to question him about the unexplained disappearance of Tony Sentance, former employee and leader of a child trafficking gang that operated from within De Vries Industries. De Vries is obsessed with the identity of his father, never disclosed to him by his mother. He enlists the help of Jackie Briggs, his former housekeeper, and Jean Rook, his solicitor and erstwhile lover, who wants to rekindle their liaison. He reluctantly agrees. Agnes Price, a young primary school teacher, becomes concerned about the welfare of one of her pupils and Leonard Curry, a schools attendance officer sent to investigate, is attacked. Shortly afterwards, Leonard's niece, Audrey Furby, goes missing.
De Vries is the sequel to Sausage Hall. The two novels can be read as a pair or each as a standalone text.
