Paul Ernst’s 1939 The Sky Walker is the third volume in the Avenger series. The Sky Walker was published under the Kenneth Robeson house name.
One day the glasses in Chicago’s Mike’s Bar begin to sing, then shatter for no obvious reason. The mysterious phenomenon is accompanied by a seemingly causeless droning from the sky.
Chicago is distracted from the mystery by real tragedy. A pavilion collapses, killing seventeen people. The cause appears clear: substandard steel used in the supports, no doubt thanks to a greedy contractor.
But this is not the cause at all. Evil! Evil is the cause! It’s up to Richard “the Avenger” Benson and the increasingly large staff of Justice, Inc to reveal what is really going on.
