Thirteen Guests - J. Jefferson Farjeon

A country house mystery with quite a few deaths, a convuleted solution of the murder mystery and two characters, who didn´t serve any purpose at all besides

 

being the mandatory love couple, who just have to be in a proper golden age mystery. At least it felt like it.  

(show spoiler)

 

Overall I enjoyed reading this book, even though it started dragging towards the end.
