Perfect Witness

During Dangerfield's examination of Jayne Sharman it transpires that she was raped six weeks earlier. By an apparent coincidence, one of Dr Robbins' patients, who is recovering from hepatitis, was also raped. Then Jayne is rushed to hospital with hepatitis. The police suspect a link between the two cases, but with one victim dying and the other refusing to give evidence, they have difficulty in bringing the case to court.
