The Harder They Falll is the 337th episode of The Bill.
P.C. Loxton is attacked after a break-in at a night club and helped by a cabbie who is a special constable. Loxton blacks out and can't remember the incident. One of his attackers later dies. Most of his colleagues think Loxton is lying about the memory loss. Det. Supt. Meadows is back leading the murder squad.
