If the information you are referencing has been obtained from the 6th edition, then you ought to reference that copy rather than the older one.
In this case, you would reference the chapter author as outlined in the Harvard Referencing guide on the library website
The example given is:
Chapter authors in edited works References to the work of an author that appears as a chapter, or part of a larger work, that is edited by someone else, should be cited within your text using the name of the contributory author not the editor of the whole work.
In his work on health information, Smith (1975) states ...
In the reference list at the end of your document, you should include details of both the chapter author and the editor of the entire work.
Smith, J., 1975. A source of information.
In: W. Jones, ed. 2000. One hundred and one ways to find information about health. Oxford: Oxford University Press. Ch.2
Mike Fray should be listed as the author if you are referencing the 6th edition.
