Vengeance On Tyneside [EPUB ebook] 

Two young women are stabbed to death in Tyneside. But what’s the connection?
After a trip to the coast, Agnes Lockwood is shocked when she finds a young woman tucked away behind the litter bins in Newcastle Central Station. DCI Alan Johnson and Sergeant Andrews quickly set up an investigation.
They soon learn that this is only the first case of its kind, when another stabbing takes place on the Newcastle quayside. Naturally, Agnes is keen to help with the investigation.
DCI Johnson insists that she stays away from the case, but Agnes has never been a woman to be put off so easily.
