Overview:Life at the Yorkshire veterinary practice continues to challenge the partners, whether by neglected animals or tight-fisted farmers. There are domestic challenges for Tristan, however, when James and Helen play a practical joke with a "Welcome Home" card from an old female admirer. Life is never simple when true love or the demon drink rule Tristan's life, and he is soon in trouble with Siegfried. A new housekeeper, Mrs. Alton, has been recruited by Siegfried to keep a watchful eye on Tristan, who, dispatched to tie up the details of her employment, is delighted to discover that Mrs. Alton is a rather attractive young widow. But this is not the Mrs. Alton that Siegfried had in mind.
