The Bill: Cast No Shadow/Betrayal. Investigating an attempted abduction leads DS John Boulton and DC Jim Carver to a crime syndicate in Manchester - where Carver is decidedly surprised to find that one of the top men in the organisation is his former DI, Frank Burnside (Christopher Ellison). Has Burnside really gone to the bad? Or is his current position somehow connected to the mysterious overnight secondment he was pulled from Sun Hill for five years earlier? The Bill's most iconic character returns to the series in this excellent two-parter.
