Tiffy Moore is searching for a place to live; she has been living in the flat of her ex-boyfriend, Justin, even though they broke up and he has told her that she needs to move out. She needs something inexpensive, and soon, so her options are limited. While touring a flat with her best friends, Gerty and Mo, they discuss how badly Justin treated Tiffy and their concern about her finding a suitable place to live; the place they are looking at is awful. Tiffy tells them about an ad in the newspaper seeking a flatmate in a one-bedroom apartment. The tenant works nights, so a flatmate who works a typical workday could use it during the hours he is not there. Mo and Gerty are skeptical of this arrangement, but the apartment is in a good location, the rent is cheap, and Tiffy’s other options are not good enough. 

Tiffy goes to work at the publishing company where she edits books on crafting and DIY projects. Her current client is Katherin, who has written a book about crochet.
