It's not a good time to be a patient at Stockport's Stepping Hill Hospital. While detectives swarm over the place looking for clues to the deaths of three patients from saline drips contaminated with insulin, another crisis looms.
In the latest incident, officers were called to the hospital at 20:30 BST on Saturday after staff found that a bottle of milk had been contaminated.
However detectives said there was no evidence of a link to the sabotage of saline drips earlier this year.
For readers of crime fiction, there is a distinct frisson from the fact that a milk-bottle spiked with bleach had been left on a ward - precisely the method by which someone is murdered in a hospital in an early book by one of our foremost authors of detective stories*.
And a quick trawl through Amazon turns up another bit of light reading: 'Insulin Murders' by Caroline Richmond and Vincent Marks.
Insulin Murders is the first book on the market to describe real life cases of murder using insulin (and other hypoglycaemic agents) as a murder weapon. Written by a leading authority on insulin and its use as a murder weapon, this is a gripping account of true life crime, intended for doctors and laypeople alike.
It will appeal to both the medical and non-medical communities, and especially to all those with an interest in forensic medicine or true life crime.
And - just possibly - potential murderers as well.
*Spoiler Alert; this one.
