The police catch Floyd but criminal psychologist Fitz is unable to make a breakthrough before he has to be released due to lack of evidence.

Floyd's audacity grows as he phones Fitz on his radio show asking how a rapist should cover his tracks.

Fitz privately advises a patient who seems to be having problems with her husband.

Fitz's advice, for which he charges her £50, leads her to conclude that she should leave him.

Fitz is asking DCI Wise to replace him with Irene as the killer may stop killing if she realises she is not getting the shrink's undivided attention.

Irene agrees to change, but finds the nature of the job, and the pictures of her dead students too much to stomach and goes missing.
