Donna and Ross agree to help Viv's search and they go to an empty house belonging to Freddie and find a pile of unopened bills addressed to Viv. Donna wants to tell CID, but Ross urges her to play it cool, as they weren't on duty. Donna tells Viv that she will tell the investigating officer but makes her promise to stay put. Viv immediately flouts Donna's wishes and heads to the house with Bob to retrieve the post. (thetvdb.com)
