This is an excellent series!! Not only is the murder investigation suspenseful, but there are also the underlying plots of Helma's relationship with Police Chief Wayne Gallant, and her relationship with Boy Cat Zukas (a stray which decides to adopt her). Also, her artist friend, Ruth, is really a "hoot"!! Just about the direct opposite of Helma. Besides the solving of each murder mystery in each book, Jo Dereske gives "just a nibble" regarding the relationships with the reading of each of the books in the series (5 at present) to "keep you hooked". I found that as soon as I finished the first one, I had to pick up the next and so on. I am anxious for the new one to appear!! They are very entertaining for someone looking for light and good mystery reading. And, "Out of Circulation" (the latest one out) was excellent!! Really kept you guessing right up to the end as to who the "bad guy" was.
