Dr. Charlotte Brown, the doctor who delivered Annie's baby, has a different problem. The Pacific Dispensary for Women and Children, the clinic and hospital she co-founded, is being threatened by financial and legal difficulties caused by the mysterious illness of a former patient.

When Annie takes up the challenge to help Dr. Brown and the dispensary, she will discover that getting back into the business of investigating crimes is exactly the remedy she requires.
