The Wary Heart
Jan Carron goes to Shamlee, to care for her sister's twins while Chris and Tom go to America.
On the train she meets Tim Greig, the local vet. To her consternation she learns Mike Maxwell has returned to Shamlee. He disapproves of Jan's friendship with Tim, yet he shares a bond with Angela McCall, whose son bears a resemblance to him, and to Jan's own son.
