Once when Benet was about fourteen they had been alone together in a railway carriage – and Mopsa has tried to stab her with a carving knife.  It had now been some tome since  Benet had seen her mad mother. So when Mopsa arrived at the airport in a dowdy grey suit, looking drab and colourless, Benet tried not to hate her.  But then the tragic death of a child begins a chain of deception, kidnap and murder.
