Fill in Blank Game II

Let's try another game this week. I am going to list partial titles and you try to fill in the blanks. 

All the books are by the same author which is a clue. At the end of the titles, supply who the author of all the books was. I will give you a hint that these are not new books - they have been out for a while.  This should be a challenging game for mystery buffs!

You are on the honor system playing this - try completing this without the aid of the internet.  In a few days I will fill in the blanks and you can post how many you got right in the comments.  I did this in a very low tech sort of way :-)


1) The Siamese Twin Mystery


2)  Halfway House


3) The American Gun Mystery


4) Calamity Town


5) Cat of Many Tails


6) The Case of the Seven Murders


7) The Origin of Evil


8) The Scarlet Letters


9) The Finishing Stroke


10) The French Powder Mystery


The Author of all these books is Ellery Queen. 


ENJOY!!!
