"Fans of Phillip Mercer, sometime geologist, sometime soldier of fortune, won't be unhappy with this latest installment in the series. Once again, Mercer is portrayed by J. Charles, who has a clear, resonant voice. This time Mercer is called upon to unearth a seventy-year-old secret that is linked to a current act of terrorism. DuBrul cleverly offers an alternative explanation for the 1937 destruction of the Nazi zeppelin HINDENBURG at Lakehurst, New Jersey. Charles is at his best portraying newsman Herb Morrison, who witnesses the catastrophe and describes it as it happens. Charles is less successful at playing characters with accents. Most sound contrived. A.L.H. (c) AudioFile 2007, Portland, Maine"
