Occasional stories using recycled characters. A note: "Susan & Jake, NIS" is really the second story in this series, but since it's also in the NIS universe, it can't be in two places. But characters in "Gold & Silver" first appear in "Susan & Jake".

These are all stories in what I call the Ali Clifford Saga. It's a saga, not a series. The difference is that -- to my mind, at least -- a series has the same main characters. A saga, on the other hand, is composed of books each of which has its own main characters. However, characters from other books in the saga appear in roles major and minor.
