I have been reading my Agatha Christie books. Love those books. There is a ring in one of them that was an ‘old Victorian’ ring they found. It had a diamond, emerald, amethyst and ruby in it. D. E. A. R. Dear. How wonderful is that??? They also have some other things that appear for an older time frame. A lot I have discovered works for today. I saw an ad for olbas oil and it reminded me of another of her books. Just little things I see can bring one of her books to mind. From rings, to medicinal oils to trains. If you like mysteries… you really ought to give her books a shot. There is a wide variety. I have enjoyed most of them. I particularly like Ms. Marple but the others are good as well.
