A senator from the United States is about to visit Oldcote Parish Church, and it's a Task Force job to see that he is protected and nothing untoward is going to happen. It's a job that is not to be taken lightly because the senator has been receiving threats for quite some time. Someone seems to be out to kill him. Preparations are made and safety precautions are taken but ultimately Thamesford CID must accept the fact that there is no such thing as fool-proof security.
