New Year’s Day and 1970 begins with a body on an Oxford canal towpath. The start of the new decade sees new relationships blossom and old friendships challenged as fatality strikes a ground-breaking college project, a family Indian restaurant is devastated by murder, and an all-women Oxford college is struck by tragedy. From the waterways of Venice to the streets of Oxford, 1970 brings a new evil and the ultimate test to our Castle Gate CID gang from which they may never survive.
