Lap up this new series while you can; the Beeb have reportedly cancelled any further runs... In this two-parter series opener, Boyd is unsettled when Sarah Cavendish (played by Five Daughters star Eva Birthistle), an officer of equal rank to him, joins the team to investigate the disappearance of a banker who had been struggling to cope with losing his daughter to cancer. Though Cavendish's professional skills quickly prove to be a major asset, her new colleagues discover that a failed operation from earlier in her career is continuing to haunt her, and become concerned for her welfare. Trevor Eve stars in the first of a two-part story kicking off the final series of the crime drama, with Sue Johnston and Tara FitzGerald. Continues tomorrow.
