I hadn't heard of Shirley Bellwood either,
have now added her to my list of Artists of note.
In Memoriam: Illustrator and Comic Artist Shirley Bellwood

Quote: [' One of Shirley’s drawings for The Unremembered Inn. Author Max Harris tells me this depicts an actual event from real life – in the prison in Gloucester Castle on 16th June 1677. Mary Ellery is pleading to save the life of her husband William, imprisoned for debt. “I gave Shirley just a brief description of the events which took place in the prison cell on that day,” says Max, “and was absolutely astounded at how accurately she interpreted the scene in William Ellery’s cell (including the rat!).
“She was a most remarkable and gifted artist and it was a great privilege to have met her.”]
And here is a gallery of her MISTY covers.
