Research phase 1: books arrived

According to my plan, I have purchase my books at the end of September and they have just arrived last weekend. 

My book list: 

-'Unmasking the face', by Dr. Paul Ekman and Dr. Wallace V. Friesen 

-'Emotions revealed: recognizing faces and feelings to improve communication and emotional life', by Dr. Paul Ekman

-'Telling Lies: clues to deceit in the marketplace, politics, and marriage' by Dr. Paul Ekman

-'Detect deceit:how to become a human lie detector in under 60 minutes' by Dr. David Craig 

I didn't write the last book in my plan. However, I purchased it because I wanted to have a book from a different author to make my research more accurate and reliable.
