Agnes Turner's boring life in her retirement flat changes when she spots Amy Horrocks running down the road in terror. Agnes takes her in where Amy sobs she fears for her life - and reveals her terrible a mercy killing, for which she is now being blackmailed.
Although this was published before the death of Anthea Cohen, it doesn't feel like one on of her books. Agnes behaves in some odd ways and doesn't dish out her usual brand of punishment. I have to say if I lived with Amy Horrocks I think I'd have been tempted to 'bump her off'. She really is extremely annoying.
