I hadn't read the first book in this series (at least according to Goodreads, but the character sure felt familiar). I will be looking for "McDeath" to read though because I quite enjoyed this book. There were issues (didn't see a lot of character development (part of the first book?), story was a big convoluted, took some time to ) but I overall liked Ivy Meadows (real name Olive Ziegwart) and her zany antics (car catches fire? No problem, that's why she carries a fire extinguisher.)
The mystery is that several residents of a retirement community seem to be committing suicide. And Ivy, as a part-time consultant in her uncle's detective agency, is asked to help. She's also house-sitting and performing in a mash-up of "The Sound of Music" and "Cabaret." There was a lot going on in the book (also Ivy has a brother (with whom she has a complicated history), she's dating a new guy, and... and... and...). It crossed zany into overwhelming a few times but I plowed through the book in one sitting and was fairly happy when it was done.
