DEATH'S BRIGHT DART
By
Dr. Davie finds mysteries a form of high-browsing and in his second appearance here he is faced with the mysterious death (by poison dart?) of a colleague who had once performed his laboratory experiments in a concentration camp. Once again the suspect list has more letters than the alphabet (Ph.D.'s) as the author takes his tricky time about making X and Y into Z. For the educated guesser.
