Based on Kerry Greenwood's book 'Unnatural Habits'. The gothic world of the Magdalene Laundries - a halfway house for pregnant and wayward girls, run by Catholic nuns - sets the scene for the tragic death of an escaping teenager. AS Phryne becomes more suspicious of the goings-on behind the convent walls, she and Jack realize the threads of this crime lead higher up and closer to home than they ever suspected... The return of Jack's father-in-law - now Chief Commissioner Sanderson - his ex-wife, Rosie and her dashing beau - offers a chilling insight into extent of police corruption in Jack's hometown.
