London Bridge is Falling Down

Description

When 91-year-old Amelia Hoffman died in her top-floor flat on a busy London road, it's considered an example of what has gone wrong with modern society: she slipped through the cracks in a failing system. But detectives Arthur Bryant and John May of the Peculiar Crimes Unit have their doubts. Mrs Hoffman was once a government security expert, even though no one can quite remember her. When a link emerges between the old lady and a diplomat trying to flee the country, it seems that an impossible murder has been committed.
