Hospitals are places of safety, where staff help people to get better. So the parents of four children left in the care of Beverley Allitt never imagined that she’d harm them. The 22 year old nurse was convicted of their murders and harming 9 others on Ward Four at the Grantham and Kesteven hospital in Lincolnshire in 1991.

Police worked out that Allitt was the only person present for all of the unexplained collapses and that she had reported the key to the insulin fridge missing.

Childhood friends and nurses she trained with later told of her self-harm and bizarre behaviour including finding faeces in the fridge.
