Following the dissolution of Oxford City Police and the merging with Thames Valley Constabulary, the latest instalment is set in 1969 and picks up with the team dispersed as they find their feet in their various new roles. However, despite their separation, the tragic murder of DC George Fancy still hangs over them both collectively and individually, with the case remaining unresolved. With their new positions also come new colleagues and responsibilities. Thursday must adjust to working with new boss DI Ronnie Box and junior DS Alan Jago. Meanwhile, Joan has settled back in Oxford and is training to work in social services under the mentor of new manager Viv Wall.
