I read this series a number of years ago and was just reminded of it. I really enjoyed the books, they're not overly complicated, and it has a bit of whimsy. Helma is a librarian who keeps stumbling into murders, uncovering the clues and solving the crime before her policeman beau can do it. Typical cozy fair, but enjoyable and somewhat generic.
I'm not sure what to think about this one - it started off with Miss Zukas being so prudish and prim that it wasn't enjoyable to read, but I could see character development as the story progressed. I guess the culprit almost from the beginning, but it was still a great storyline.
