If you have read all the works of Agatha Christie and P G Wodehouse why not try a mixture of the two in this delightful series?  Each book manages to be rather different than the others and after taking a break from the house party murder format here it is again and welcome when it is done this well.  There are a large number of people involved and you will doubtless need to refer to the useful (no, try indispensable) family tree at the front to keep track of who is (or was) who.  This can get a little muddling at times, but serves to keep the reader on their toes and prevents the story from being too linear.  It also serves to fill the pages with countless sub-plots presenting a dizzying number of possible suspects, making this an exciting and involved story, just the way I like them.  Long may this highly entertaining series continue.
