Oliver's Travels

Though Oliver is bound for the Orkneys to find Aristotle, Diane declares she is only going as far as Shrewsbury. But after some successful undercover work there, Diane decides to travel a little further with Oliver. He takes her to the deserted mining town where he grew up. Then she takes over the wheel.

Diane decides to make her connection to Oliver temporarily permanent and the couple exchanges "vows" on sacred ground. They begin their "honeymoon" at an inn with a proprietress who is delighted to play along. Next day at Hadrian's Wall, their union is blessed with the surprise appearance of a son. They plot their next move when Oliver discovers that Aristotle is giving them clues to the mystery in the crosswords.

At the palatial digs of the groovy Baron Kite, Oliver and Diane discover the link between the murder victims and the Farquhar Group. The hospitable baron follows up with an aerial assault. Only divine intervention gets them on the Orkney boat. Meanwhile, Michael discovers that his hacker friend is still in jail, but has left behind a girl as talented as he is.
