I highly recommend a relatively new read, "Dear Cary" by Dyan Cannon. Cannon was married to Cary Grant after a lengthy courtship/relationship. It is intriguing to read how Cary saw her on a tv show and pursued her until she fell in love with him.
He more or less insisted that Dyan try the drug or their marriage would fail. It failed anyhow and Dyan ended up in a mental hospital after having a nervous breakdown!
The book is a great look into the private life of a guy that oozed class onto the movie screen but in real life was a skeleton in his own closet (isn't that a clever line!?).
Dyan Cannon has long since gotten over her life with Cary Grant and has gone on to lots of interesting things in her show biz life. This book is an easy and fascinating read on one of our legendary favorites.
