I just finished this one last night.  I really like this series and I think this was the best one yet! It had the English Country Manor murder mystery feel to it, with still the bouts of humor typical of a cozy.  There is a not a very nice victim, a house full of guests, all or several of whom have motive, means, and opportunity.  A few nice red herrings to make for fun twists and turns.  There is also some movement on the romantic sub plot side of things and even on the overarching mystery of the family treasure 🙂  Don’t want to say more and give anything away.  This was a fast paced cozy with lots going on in.  I really enjoyed it.
