7th entry - ending

The ending of this book i thought was very good.  I liked how the suspense was finally drawn to a close and i thought that Vera was the killer.  This was then a huge suprise when i found out that Wargrave was actually the killer which greatly suprised me.  I however thought that the way he planned so intensely was amazing and that he had some incredible problem solving skills.  I greatly liked this book and thought that it was very good.
