- “I love you more than fairy tales” was what Toby traditionally told him instead of “good-bye”. 
Events in the Series (Spoilers) Edit
Use the book title at the opening of each paragraph as a "Spoiler Warning". (The purpose for this section is to be able to find things in a given book once you are past the book and can't recall what —therefore in need of a refresher and/or need to know where to look it up).
✥ In Rosemary and Rue, Cliff calls while Toby is on stake-out, asking her to bring chocolate ice cream home. Their daughter, Gillian Marks is listening with keen ears that she got from her mother who is half faerie—though neither Cliff or Gilly know it. After being released from a spell that turned Toby into a fish for fourteen years, she went to see Cliff. She couldn’t tell him where I’d been or what had happened, so she told him that she had amnesia due to being attacked by the man she’d been tailing. He hung up the phone. Both Cliff and Gillian refused to see her or talk to her every time she tried.
