Dorothy Martin's husband, a local police inspector, is out of town. On a trip to London for a doctor's appointment, Dorothy talks to a young man who, by the time the train reaches Victoria Station, is very dead. No one seems to think anything is amiss and the man who told her he was a doctor and would take care of everything seems to have done just that. The body has disappeared. Dorothy has a mystery on her hands and, with her husband in Zimbabwe, there's nothing to do but begin an investigation. She insinuates herself onto the staff of a computer software company and discovers not only a surprising killer but the lengths to which someone might go for the sake of a dream.
