Notes: Divided into [Chapter I,] (pp. 1-11); Chapter II, "Murder Strikes Again!" (pp. 12-21); Chapter III, "Startling Discovery!" (pp. 22-33); Chapter IV, "The Doom!" (pg. 34-38); and Chapter V, "The Pay-off!" (pp. 39-46).

Syd Shores drew the entirety of page 1 and then the last 2 panels on page 46. That seems to be it.

I would add the first 2 panels of page 2. I have always wondered if the rest of this wasn't penciled by Burgos? - JVJ
