1. The husband is a flat out idiot! I literally had this thought multiple times throughout the book while rolling my eyes. 
2. I didn’t figure out the ending, tho I was constantly going back and forth between several scenarios as to “who done it”.
3. This was a quick read, that kept me on the edge of my seat while trying to solve everything.  Call me a prude, but the language was a little too foul for me.
