When daring journalist Sir Percival Harris gets wind of a curious crime in a sleepy English town, he ropes in his old friend Professor Ernest Drabble to help him investigate. The crime is a grave robbery, and as Drabble and Harris pry deeper, events take a mysterious turn when a theft at the British Museum is soon followed by a murder. The friends are soon involved in a tumultuous quest that takes them from the genteel streets of London to the wide plains of the United States. What exactly is at stake is not altogether clear - but if they don't act soon, the outcome could be a bloody conflict, one that will cross borders, continents and oceans. Meanwhile, can Drabble and Harris's friendship - which has endured near-death experiences on several continents, not to mention a boarding school duel - survive a crisis in the shape of the beautiful and enigmatic Dr Charlotte Moore?
