I will start this review by saying that this book, book Three, was my first introduction to Gladys Gold and her "girls," and some of the side plots were continuing from the previous book, but I didn't/don't have the context for those side plots. That might have changed the way I looked at some of what I disliked about the book.
To start with, I really enjoyed reading a book with senior citizen characters! Each of the main group of characters were fleshed out with backstories and felt like real people. Even the side characters you don't see much that rely on quirks to make them memorable still felt like real people. The setting, the quick wit, and the humorous writing all worked well to really draw me into the story and to have fun with it.
It was not always pleasant to read, but I did appreciate the honest look at grief, how it can linger far longer than what people think it's "supposed to." How it can affect a person long after they've apparently moved on in every other aspect of their life. How losing someone you love and grieving can be a bad breakup, not only death. It's not happy, but it's real.
It's not often, in my experience, that you run across a cozy mystery that utilizes a group rather than only one or maybe two protagonists. I enjoyed the way the group worked off each other, some contributing more than others, and how they all seemed to care about each other even in their selfish moments. The mystery plot was also rather good, and I liked the "Columbo" aspect of essentially telling us up front who the murderer is and then showing how the "detectives" solve the case.
While I did enjoy the tale, the "split-personality" thing didn't quite hit the mark for me, but it was not horribly offensive in my opinion or distracted too much. Not great, but not awful.
The worst thing, in my opinion, was everything about Gladys' boyfriend/ex-boyfriend/whatever he was. I really disliked pretty much everything to do with him. Maybe reading it out of the context of the previous book made it seem worse than what it was, but while Gladys did make a mistake and was not perfect, he was... well, a jerk. He felt extremely manipulative, and instead of communicating like a mature 70+ year-old, he gives her the cold shoulder and sulks like a bratty teenager. Gladys' mistake was, in my opinion, a reasonable mistake. When going somewhere that was difficult to reach and alone with only one other person, she went against his wishes and told someone - the wrong someone who then ruined everything in a panic - but I completely understand her reasoning. Even when she attempts to apologize to make things right, he lays down a drastic ultimatum (test?) and is then further angered when she hesitates and even pushes back a little. To be completely honest, I would not be surprised if kind-of-boyfriend Jack turned out to be some kind of, at least, controlling partner or even a killer, himself.
I would like to read more of these books, and I think I will start with numbers 1 and 2 and see if my opinion on Jack changes with further context.
