Goof identified Ms. Higgins as the artist on "Super Detective Library 96 - Vic Terry-Riddles of The Ring"
There is very little/hardly any info available but these links might start someone searching for more on an artist new to me:-

Interesting to see Hilary Bailey mentioned as a writer for girls comics.
She was Michael Moorcock's wife and had three children by him.
Interesting career herself.

Sorry to be rather late in adding my twopenn’orth to this, Paw, but I’ve only just found this bit of the Forum.

Here’s a probably incomplete list of Mollie Higgins’ work for other girls’ titles:

Picture Stories
Princess Comic 1960-1961: Pam and Peter 
Princess Annual 1965: The Secret of Seddon Hall
School Friend Annual 1963: Pat of the Dolphins
School Friend Annual 1964: Camera-Mad Carol
June Annual 1965: The Secret Island
June & School Friend Special Extra (a Holiday Special) 1968: Noel Raymond, Detective

June & School Friend Picture Library 565: Sal and Co Go Sleuthing
Schoolgirls Picture Library 263: School on the Lake

Text Stories
Various story illustrations:
Girls Crystal Annuals 1963 & 1964
June Annual 1963 & 1965
Sue Day Annual.

Text story versions of several Russian/European fairy and folk tales (Spectacular full page painted art, and for me the best work she ever produced. The thumbnail on encyclo-bd doesn't do it justice):
School Friend Annuals 1964, 1965, 1966
June Annuals 1964 & 1965.

Virtually nothing is known about her life. She started working on Romance titles in the mid-1950’s, later moving to the younger girls’ titles to do the stuff listed above. You’ve already linked her 1966 work for Diana. After this, she simply disappears.
