Rob Bradshaw of BiblicalStudies.org.uk sent me the following note:

Thought that you would like to be the first to know about this article: The Pastoral Epistles and the Mind of Paul by Donald Guthrie.

This is an excellent short monograph from Guthrie that interacts with P.N. Harrison's view of the authorship of the Pastorals. It is hard to find in print (ask me, I know) so do please check it out.

FWIW, I have an entry for the monograph in the Bibliography (Books) section.
