This could be quite amusing – but you have to be prepared to put the work in to read it. And I found it a hard read.
The concept of having a group of 80 somethings team up with a couple of teenagers (who can do the running around and get jobs in the nursing home as undercover sleuths) is interesting.
The actual crime that they investigate is ok – although the perpetrators are obvious from their first mention.
They all suck as far as tailing someone – they are advised at the end of the book that they need to take a module in how to do it!

I found it overly wordy – chunky and clunky.

I liked the fact that the main characters were all in their 80s – and there were plenty of them.
I’m going to assume that there will be more of the Senior Sleuth Mysteries in the future. Hopefully without having to do lots of introductions they will be easier reading.
