Mr. Chameleon - The Case of the Woman Who Sensed Murder

The Police Commissioner is reading a letter to Mr. Chameleon.  The letter is from an Helen Audrey, a wealthy older woman that believes that someone is trying to kill her. She knew Mr. Chameleon and his mother many years ago, and would feel better if he would come to visit her.  As soon as Mr. Chameleon arrives, he meets her doctor leaving the home.  The doctor tells him that Mrs. Audrey is dead.  She was showing the signs of an overdose of heart medication.
