We’ve been asked about the chronological order of the stand-alone stories for the character Portia Manning (of Portia Faces Life fame).
This is the way to go:
The Haverlock Affair
Partners In Jeopardy
The Silent Witness
The Seed of Evil (available shortly)
followed by the shows in which Portia makes a ‘guest appearance’:
30 Days Hath September
Violets Are Blue
Hope this clears up any confusion.
