Can anyone help me with the last three. Who is the author of the series of books about forensic pathologist Dr. Sam Ryan (Ican find dvds, but not books). In the novel "Faceless Killers, by Henning Mankell, what word does the old woman at the start manage to gasp out as she dies? In which Agatha Christie novel does Poirot sacrifice his famous moustache to masquerade as his own brother? Any help much appreciated.
