At the same time as solicitor Lennox Kemp takes on, against his better judgement, a lucrative request to trace missing Sieglinde Prentiss, his assistant Franklyn Davey is helping his fiancee Dinah to come to terms with the tragic loss of her college friend Annabel Angus - presumed dead in the carnage of New York's World Trade Center. Franklyn and Dinah's attempt to retrace the last days of Annabel - a high-flying Glasgow reporter - take them on a journey to the Scottish Isles. Kemp, meanwhile, has hired the services of private investigator Harry Pocket to help him discover the whereabouts of the ex-Mrs Prentiss, in a quest which will become increasingly comples and sinister. Two missing women. Two mysterious disappearances. Two separate cases for Messrs Kemp and Davey - or is there a link between them?
