Critical Conditions is the 5th book in the Dr. Alan Gregory series. It started off really good. His patient, Merritt, is a 15 yo girl suspected of murder. However, she is remaining silent and Alan and his detective friend are trying to find out what happened without her help. The book started going downhill when she started speaking again to tell Alan the truth to what happened. It just seemed a little far-fetched. 3.5 stars
