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.
