There is an old saying, “An apple a day keeps the doctor away.” Unfortunately, someone has been eating too many apples, and the world famous doctor E. R. Smith has been away from her office and no one has been able to find her. One of her patients is terribly ill and only Dr. Smith will be able to cure him. The only clue to her whereabouts is a locked box and some papers in a patient’s file. It is your job to unlock the box and discover where she went before it is too late.
