Files of the Missing

People are always going missing-some accidently and others on purpose. Files are kept on these people until their cases are closed, but some will never be solved. The team were asked to go to the Isle of Wight to oversee an Indian diplomat's visit, and whilst there, Percy told of the disappearance of a woman, an acquaintance of Alicia's, who had left her daughter at the bookshop for Granny to look after until Alicia came back. No one knew where Sandra had disappeared to, leaving behind her child and husband.
Later on, a father reported a missing daughter, his eighteen-year-old had been missing for six months. This was a puzzle James and Alicia could not let go; several ideas came up but proved fruitless in the search. If foul play did not happen, just how does a young woman disappear? No one had seen or heard from her for several months; they hoped the explanation was not sinister.
Their lawyer friend asked the team whether they could look into a nursing home death. There had been unexplained deaths, and the patients were frightened. Percy recognised the nurse under suspicion-could he catch him out? There were signs also that their old enemy, the Sahib, was issuing orders from his jail cell to cause harm to James and Alicia. A fire bomb was thrown into the office. Could this be a sign for their future? Would they always be looking over their shoulders?
