Again, the author of Dr. Angle's Island (1961, p. 846, J-286) demonstrates his skill in gradually unwinding a mystery, dropping many clues along the way. Nearly deserted Dagger Bay is an eery, realistically etched background for the events which follow closely upon each other. Two teen-aged sleuths, Kelly McCly and Biff Herring, stay in an old mansion while trying to get a story about the ghost ship which has been seen in the bay; at the same time, Kelly's father is assigned to report on an immigration problem. Tension is maintained from beginning to end, and a solution is reached which seems possible. The days of the red-sailed ship-- the past, and the days of the phantom-- the present, become entangled, and then disentangled. A cleverly lotted mystery, far above average.
