The Vulcan Academy Murders
Jean Lorrah
 Captain Kirk and Doctor McCoy travel to a hospital facility on Vulcan to acquire treatment for a badly wounded Enterprise crew member. Kirk encounters Spock's mother, Amanda Grayson and soon becomes heavily involved in Spock's personal life. Then people begin to die. Kirk, trying to solve the case, is hampered by some Vulcan's belief that it would be too illogical for murder to be happening on their homeworld.
