The Mystery Squadron 

1933 - 12 Chapters


Plot


A dam being built by Stephen Gray comes under attack from the mysterious 
pilot, The Black Ace, and his "Mystery Squadron" of pilots. The identity of the 
Black Ace is so secretive that it is even concealed from his own men in the 
Mystery Squadron. Fred Cromwell and his partner Bill Cook seek to identify the 
Black Ace and stop his attacks on Gray's construction of the power dam. 
Cromwell and Cook struggle to identify the Black Ace, as a number of characters 
behave suspiciously, including Lafe Johnson, a rival contractor to Gray; Martin, 
the hotel owner; Collins, a construction employee for Gray; and Dr. Flint.
