"In this delightful box set, four senior sleuths draw upon their professional skills to solve mysterious murders in the seemingly idyllic Sage Gardens retirement community." So wait, there are four, count 'em four murders in this one retirement comunity and no one thinks this is at all bizarre? If it were true, people would be flocking out of this community in droves. I can imagine the publicity literature for the community would say something like, "Come and live in our idyllic community - we haven't had a murder this week - yet!"
And the police are so useless, as usual, that four retirees are solving the crimes? What are their 'professional skills'? Judged by other such crappy mystery novels, they have to be: knitting, cup-cake baking, bookstore managing, and porn-movie making. Just kidding on that last one, I can guarantee you there's zero sex of any sort in any way in any of these four novels because as everyone knows, old folks don't even think about sex, let alone have any! Barf.
