A story from the collection Do Not Exceed the Stated Dose.

Trish Noble, a nurse and devotee of her local church, walks into a Bath police station and confesses to killing her husband. She found him drunk again, saw red and hit him in the side of the head with a teapot. Detective Peter Diamond struggles to see the woman as a cold, callous killer, but when the post-mortem reveals stab wounds to Glenn Noble’s back as the cause of death, it becomes clear there’s more to this case than meets the eye.
